New in nanoCAD 24

Version 24

A new functional toolbar Layers has been implemented for quick manipulations with layers.
You can open the toolbar in the ribbon interface in the Home and Settings tabs:




In the classic interface: menu View Toolbars > Functional image005.jpg  Layer Manager… or in the Properties bar – image005.jpg  Layer Manager
The command for opening the Layers functional bar in the command line – LAYERSQUICK.
The list of layers can be presented in a tree or table view:



In the tree view, the names of layers are displayed in the left column, and the main properties in the form of icons are displayed in the right column (Status, Color, VP Color, Layer Visibility, Freeze, Lock, Plot, New VP Freeze, VP Freeze). The remaining parameters are expanded in a list under the layer name when you left-click on the arrow to the left of the layer name. The default display mode is a tree view.

In the table view, layer properties are displayed in the form of a table with columns; the functionality corresponds to the Layers dialog.

Due to addition of the Layer Manager functional bar, the old Layers dialog has now become modal, i.e., while the dialog displays all relevant information on the layers in it and changes outside configure dialog are not taken into account. The bar synchronizes and displays current data after closing the dialog.
A new CAD Standards toolbar has been created, which includes such commands as: image008.jpg  Standards settings, image009.jpg Configure, image010.jpg Check, image011.jpg Layer Translator.
The LAYTRANS command has been added. The Layer Translator is designed to convert the layers of the current drawing in accordance with the standards specified for layers. You can also use the Layer Translator to visually control the contents of layers and to remove unused layers in a drawing.
The command opens the Layer Translator dialog box:


The following functional toolbars have been updated and improved:

  • Coverings browser (COVERINGBROWSER)


  • Covering editor (COVERINGEDITOR)


  • Texture editor




The possibility to lock and unlock layers has been added to the Drawing Explorer functional bar. To do this, in the Layers group, click the lock icon while holding down the CTRL key for the selected layer.


The possibility to redefine blocks has been added to the File Explorer functional bar. The Insert and Redefine and Redefine only commands are available in the block context menu image018.jpg.


A new Centroid object snap has been added – snap to the center of mass of closed objects (circle, ellipse, polyline, spline, region, block). You can call the one-time Centroid object snap using the GCE (geometric center) keyword.


A new AREA command has been added to the Inquiry toolbar to calculate area and perimeter by specifying points of an area or an object.


The Area (AREA) and Cumulative Area (CAREA) commands now calculate area, including for objects of the Region (REGION) type.

The Preview… button has been added to the right side of the Plot and Page Setup dialogs, which opens the Preview dialog that can be expanded to full screen.

The Preview… button has been added to the right side of the Plot and Page Setup dialogs, which opens the Preview dialog that can be expanded to full screen.

The behavior of the Plot dialog when there is no plotting device (printer/pc3) specified in the document has been fixed. The Internal PDF-plotter will now be used. In this case, whenever possible, the format dimensions and orientation specified in the pc3 file or document are preserved. The Internal PDF-plotter will select a format that exactly matches the size specified in the document or pc3, or the next larger one from the list of formats available for that plotter.

The Internal PDF-plotter will select a format that exactly matches the size specified in the document or pc3, or the next larger one from the list of formats available for that plotter

In the OPTIONS dialog box, in the Import/Export and Print Settings section, a new option has been added: Plot temporary hidden objects:

In the OPTIONS dialog box, in the Import/Export and Print Settings section, a new option has been added: Plot temporary hidden objects.

It controls the printing of objects that are temporarily hidden by the HIDEOBJECTS or ISOLATEOBJECTS commands. When the option is enabled, hidden objects in temporary isolation mode (system variable OBJECTISOLATIONMODE = 0) are printed; when disabled, they are not printed. By default, the option is disabled; temporarily hidden objects are not printed.

In the Page Setup dialog, the name of the Frame Width field has been changed to the Frame Weight. The field is available when the To file mode is enabled.
The following shortcuts have been added:

  • CTRL+SHIFT+SPACEBAR – inserts a non-breaking space in texts;
  • CTRL+B – enables/disables the bold style for new or selected text;
  • CTRL+I – enables/disables italics for new or selected text;
  • CTRL+U – enables/disables underlining for new or selected text;
  • CTRL+O – enables/disables overlining for new or selected text.

It has become possible to automatically set the frame width to fit the text size by double-clicking the left mouse button on the image025.jpg element of the text input window.
It has now become possible to switch from the “text insertion” mode (text is entered starting from the insertion point) to the “text replacement” mode (text entered from the keyboard replaces previously typed text) using the INSERT key.
Color display of the positive direction of the abscissa axis (X axis) and the ordinate axis (Y axis) when displaying the grid has been implemented. This additionally allows you to navigate the editing plane.


The colored rays are directed from the origin of coordinates. Red is assigned to the X-axis and green to the Y-axis. Display is enabled/disabled when the grid is enabled/disabled (command line: GRID; hotkeys: F7, Ctrl+G).
The grid display style in form of points (GRIDSTYLE variable) has been added.


Default GRIDSTYLE = 0 – the grid is displayed as lines in model space, block editor, layouts, and paper space layouts. The following variable values are also available:

GRIDSTYLE = 1 – display of grid as dots in 2D model space.
GRIDSTYLE = 2 – display of grid as dots in the block editor.
GRIDSTYLE = 4 – display of grid as dots in layouts and paper space layouts.

You can also set up the Grid style in the Drafting settings (command line: DDRMODES, DSETTINGS, SE).


The Copy text format function has been added to the Tax format bar (command line: MT, MTEXT, MTEXTCREATE, T).


The function allows you to copy the following properties within one multiline text: font, height, style (bold, italic, strikethrough, underline, overline), skew, tracking (character spacing), aspect ratio, text color, text alignment (left, center, justify, right, distributed), line spacing, bulleted and numbered list options, paragraph options (indents, tab stops).
To use the function, you need to select a part of the text or place the cursor on the text whose formatting you want to copy. On the Text format bar, click the Copy Text Format button. Select the text to be formatted. To complete formatting, press ESC or uncheck the Copy text format button.
Attachment of the standard file (*.dws) in the profile settings to all created and opened drawings has been implemented.
You can configure the settings in the Options dialog box (Command line: OPTIONS, PREF; hotkeys: Ctrl+9) in the Standard Audit Usage section.


Options in the Standard Audit Usage section:

  • No – prohibition to attach the standard file to drawings being opened. The option is selected by de-fault;
  • Use for all documents – use the standard file for all documents being opened;
  • Standard Audit File Name <> – setting the *.dws standard file.

When a standard file is assigned in the STANDARDS command dialog box, the file will be displayed first in the list.
The dialog box of the Text decoder (TEXTDECODER) command has been supplemented with viewing the results in the form of “Before After” table, as well as the ability to sort columns in an alphabetical order has been added.


The non-dialog version of the scale list edit command - SCALELISTEDIT to be used in scripts has been implemented.


Now the ETRANSMIT command not only creates a package of files for transfer to another user, but also creates a *.eml file and automatically opens it with the mail client installed on the computer. If the user has Outlook as the standard email client, then instead of creating an eml file, the command will create a letter with an attachment.

Now the ETRANSMIT command not only creates a package of files for transfer to another user, but also creates a *.eml file and automatically opens it with the mail client installed on the computer

The generated package of files includes an information file with a *.txt extension, containing a list of all files (including folders), instructions and notes for users.
The command is supplemented with the following settings:

  • setting the root folder to form an organized folder structure;
  • inclusion of textures created and/or used in the drawing in the file package;
  • inclusion of point cloud in the file package;
  • inclusion of unloaded external references in the file package.

The command is supplemented with the following settings:•	setting the root folder to form an organized folder structure;•	inclusion of textures created and/or used in the drawing in the file package;•	inclusion of point cloud in the file package;•	inclusion of unloaded external references in the file package.

The command also includes adding 3D files in *.stl format to the package if they are in external references of the document.
A new system variable SHOWMODIFYFRAME has been added, which controls the visibility of the dotted frame around selected objects in editing operations (copy, move, etc.).


The functionality of the command to construct a circle using 2 tangency points and a radius has been improved image029.png . Now you can also specify block elements as tangents.

The set of model viewport configurations has been expanded:


The commands are available in the Ribbon: View Model ViewportsViewport Configuration and in the classic interface Menu: View Viewports, Toolbar: Viewports.

Now, when copying properties of a polyline using the MATCHPROP command, in addition to the width, the linetype generation is also copied.

The standard Coverings library has been supplemented with new textures in the sections of Wood, Roofing, Landscape Design, as well as with a new Water section.


The possibility to delete the Defpoints layer (a service layer containing control points) using the LAYDEL command has been added. During further work with the document, when setting dimensions, the layer will be created again.

The possibilities for inserting blocks into mcad objects (tables, leaders) have been expanded. Now, using the Explode Geometry command, you can also add blocks with the Allow ExplosionNo option.

The possibility to expand the expression input field in the Table edit dialog.


The possibility to install the PostGIS extension for PostgreSQL has been added to the program distributive. The extension is necessary to use the functionality of Databases when storing point clouds. If you do not plan to work with point clouds, you can skip this step during installation.


The Properties (INSPECTOR) functional bar for a block now displays the Uniform scale property that is set when the block definition is created. You can change it in the block editor (BEDIT).
The bug due to which text scaling in a cell did not work in the edit mode in the table editor has been fixed.


The bug due to which text was not displayed in table cells with vertical text direction when top center and top right alignment was selected in the preview window of the Edit table menu has been fixed.

The crash has been fixed and the platform’s performance with drawings containing external links to large ECW rasters has been optimized. Now work with the file is organized in parts (up to 64 MB). Printing of such drawings is possible from model space using, for example, the Internal PDF-plotter.
The mechanism for selecting inserted blocks in the LAYOFF, LAYFRZ and LAYVPI commands has been corrected. Now, with the Block Set > Block options, the commands also work for layers that contain a block inside a block (external reference).

The error has been fixed, due to which external references (XATTACH) with long names were being selectively inserted when multiple files were selected at the same time. You can now select many files with long names. The maximum number of references to be loaded is limited to 200. A bug has also been fixed that caused drawings to be inserted at different scales when inserting external references at the same time.

The bug has been fixed due to which some objects (nanoCAD tables (TABLE), coordination axes (SPCLINESPGRIDSPPGRIDSPARCCLINESPCIRCCLINE), slope designation (SPGRAD)) were created rotated if the current UCS was rotated relative to the WCS. Now the tables are oriented relative to the WCS.

The behavior of the Frame weight (formerly Frame width) field in the Page Setup and Plot dialogs has been corrected. Now the parameter is available only when the Fit to paper mode.

The bug due to which when pasting a cropped block via the clipboard, the block was inserted uncropped has been fixed.

Problems with isometric grid drawing have been fixed (grid lines were located at double of the distance specified in the settings).

The Find and Replace (FIND) command has been improved. Now it not only finds, but also replaces text in tables.

The mechanism for canceling actions when creating a raster (PENCILERASERFILLERASE WITH FILL) has been improved. Now every single action in the command is undone.

The bug that caused the program to stop working when a circle was selected with a block as a tangent has been fixed. The command line now displays the warning “The specified point does not match the current snap mode. Wrong point.

The bug has been fixed, as a result of which the text pasted from the clipboard did not replace the selected text in the command line, but was added to the existing one.

The possibility to use templates when importing documents has been returned. In the Options dialog, you can set the default template for imported documents. General settings (type and accuracy of units representation, drawing limits, settings for the SNAP and GRID modes; layer organization; dimensional and text styles; linetypes and lineweights, etc.), graphic objects (title blocks, frames and logos), attached dws standards are taken from the template.


A new toolbar A new toolbar Point Cloud Project Manager (NPC_PROJECT_MANAGER) allows you to manage the project created during the import of point clouds. 


The Managing Point Cloud Revisions in the Database (NPC_EDIT_DB) dialog displays all databases in the selected connection, as well as all revisions of point clouds that were uploaded to the database using the NPC_TO_DB command – Exporting Cloud Data to the Database.
New commands Hiding the Point Cloud (NPC_HIDE) and Displaying a Point Cloud (NPC_SHOW) allow you to hide selected (or all) point clouds, as well as unhide point clouds.
When creating a new connection in the Configuring Connections to Database (NPC_DB_CONFIG) command, connections check has been added to ensure that the entered data is correct.


For point clouds in which shapes were found, Shape Center Snap has been added.

A new aggregate feature has appeared – Construction.
In the Properties (INSPECTOR) bar now there is a possibility to use a slider to change the point size.

A cloud appearance when printing and rasterizing has been corrected.

Point indices in clouds have been converted to UINT64 and the limit on the volume of point clouds has been removed.

Version 23

The utility for batch purging and initial fixing of problem files has been implemented. It allows you to correct errors (AUDIT command) and clean up unnecessary data (-PURGE command) in several user-specified drawings at once. In the dialog, you can specify the required cleaning options and other program settings. The utility also allows you to supplement the processing script with drawing correction commands that will be executed in the order specified by the user.

The batch purge dialog box opens by the Batch File Processing (BATCHPROCESS) command.


The list of files selected for processing is displayed on the right. You can add files one by one or as a whole folder. On the left there is a list of commands available for execution with a list of their parameters. The checked boxes indicate the commands and actions to be performed for each file.


Purge is also performed on disabled, frozen and blocked layers.

It is possible to purge all categories provided in the non-dialog version of the -PURGE command, including: empty entries in the sort table, annotative scales, registered applications.

Batch processing settings can be saved to a new settings profile for their further use.



After the check is completed, the final report can be copied to the clipboard or saved to a separate file.
The Reorder commands image005.png button has been added to allow you to change the commands order using drag&drop.


There is also a settings button for selected folders, where you can specify whether files in subfolders should be processed.


In addition to the standard features of the -PURGE command, batch processing provides the possibility to purge external reference files (the Purge xrefs checkbox).


For example, if there are problematic files with annotative scales, you need to purge all external references at once to get rid of these scales.
Batch Processing automatically opens xref files and purges them. And then updates all external references.
New visual styles have become available with the possibility to edit their parameters and create new ones.
New visual styles:

  • Conceptual – objects are displayed using smooth shading and Gooch face style. Gooch face style is characterized by transitions between cold and warm, rather than between dark and light shades of colors. This effect is less realistic, but it better represents the model details.
  • Realistic – objects are displayed using smooth shading and showing materials.
  • Wireframe – objects are displayed using lines and curves only. Draw order and fill options from 2D solids are not displayed. This visual style does not result in repeated creation of the view when the view direction is changed, as is the case with the 2D-Wireframe visual style. In large 3D models, the time savings will be significant.
  • Hidden – objects are displayed as wireframe; lines related to back faces are not displayed.
  • Shades of Gray – objects are displayed using shades of a single color (gray) with smooth transitions.


  • Sketchy – objects are displayed with a freehand drawing effect, taking into account the Line Extend and Jitter edge modifiers.
  • X-Ray – objects are displayed partially transparent.


  • Shaded with edges – objects are displayed using smooth shading with visible edges.
  • Shaded – objects are displayed using smooth shading.
You can create a new visual style or edit the existing one in the Visual Styles Manager (VISUALSTYLES command image011.png )



Using the context menu, you can quickly apply any style to the current viewport, after which it becomes possible to observe the effect of changing the style settings in real time.


The Materials Browser and Material Editor are opened with the MATBROWSEROPEN command.


The Materials Library has been added to the distribution kit. By default, it is located in c:\Users\\AppData\Roaming\Nanosoft AS\nanoCAD x64 23.0\CoveringsLibrary\. You can change its location in the Standard directories section of the Options dialog. There is also an option to add custom materials libraries:


The Materials Library is available as a new section in the File Explorer (ADCENTER). There you can view the materials of the library and add them to the current document using the context menu command.
It has become possible to assign a personal materials to any individually selected faces of one or more objects. Thus, for each face of the object, its own materials can be assigned. Individual faces of objects can be selected while holding down the CTRL key. In previous versions of the program, it was possible to apply texture only for the entire object.

The new version has significantly redesigned the mechanics of creating and managing named views, which now remember not only the camera position, but also the visual style (new functionality), visibility/freeze state of layers, parameters of the bounding prism, position of the user coordinate system, and other parameters.

The principal innovation is the ability to manage subsets of objects that are displayed in a particular view. When creating a view, you can form a set of objects and thus create a “white list” that will be assigned to this view. In addition to this, through the software interface, you can also realize the reverse display logic based on the “black list”.

New API options for work with views allow you to create different styles of views for variable display of objects in vertical applications. Styling views makes it possible for any type of object to assign a separate display method depending on the view context (plan, section, section, diagram, etc.). With the help of styles, you can also override the basic properties – color, line type and thickness, hatch type and color, set the texture, etc. Using predefined view styles allows developers of vertical applications to achieve a high degree of automation in creating working documentation in compliance with all regulatory requirements.

In fact, new generation views are implemented in nanoCAD 23.

Like ordinary named views, they can be saved under a separate name through the VIEW command option, but a special Model space widget has been developed for quick switching:


In addition, views can be assigned to viewports both in the Model space (split the work window into work frames) and in the Paper space. At that, any of these views is just a display of one model – changing an object geometry entails changing all the viewports on which this object is displayed, including providing a dynamic two-way link between the model and the drawing.


When opening files, viewport data integrity audit has been added. When data integrity violation is detected, a dialog box is displayed prompting you to automatically fix errors:
The audit is performed:

  • if the document contains many “hanging” objects that should be in the paper space block, but are not in it. After correction, the objects are added to the block.
  • if in the layout a display boundary is set to the general viewport of the layout. After correction, the display boundary is removed from this viewport.
  • if one polyline was selected as the display boundary for several viewports. After correction, display boundaries are removed from such viewports, the polyline remains.
  • audit for storage of incorrect lists of viewports in the layout. After correction, the viewport lists are re-read from the paper space block.
In the Viewport Alignment (ALIGNSPACE) command, the ability to align any viewport to the alignment points specified in one of the available viewports has been added.
A new Arc Text (ARCTEXT) command allows you to create Arc Text type objects along a curve selected arc.




Arc text options can be specified and edited both in the Properties bar and in the ArcAligned Text Settings dialogue box.


The arc text is associated with the arc along which it is built. It changes its position and stretch with the change in the length and curvature of the arc itself.



 The arc text has its own grips that allow you to adjust the value of its offset above/below the arc and the offset along the arc from its left or right edge.


A new Rectangle from Center (RECTCENTER) command allows you to create a rectangle (Polyline object) by specifying its center and vertex.



When creating it, you can specify the length, width, area, rotation angle, chamfer size or corner rounding value.


In the Drawing Explorer it has become possible to view and change layer properties. The following icons are displayed: current layer, xref layer, on/off, unfrozen/frozen, layer color.


By clicking on the icon while holding down the CTRL key, you can switch layer options such as on/off, thawed/frozen. Double clicking on a layer sets it current.
The multiline text editing command MTEXTEDIT, MTEDIT is set to automatically restart at the end of the previous session. The final completion of the work is carried out by pressing the ESC key. You can switch to a single command call by selecting the Mode option, and then Single.


The Mode option switches the value of the new system variable TEXTEDITMODE, which controls the automatic repetition of the MTRED command.

  • 0 – Multiple. Enables automatic repetition of the MTEXTEDIT command.
  • 1 – Single. Specifies the MTEXTEDIT command to edit a single text object.


The Tracking button has been added to the multiline text editing bar, which allows you to set the character spacing:



A new property of Automatically control the measurement scale in the viewport has been implemented, available for dimensions specified in the layout.


In the context menu of the selected dimension, you can now control its precision:


The copy object properties command (MATCHPROP) now copies hatch background.
Now highlighting is removed from a raster image when it is aligned with the ALIGN command. This makes specifying points on the raster for alignment more convenient.
In the Batch Plot dialog box, it became possible to import page setups from external drawing files (*.dwg), drawing template files (*.dwt), graphics interchange format files (*.dxf), CAD standards files (*.dws).


A set imported in this way is displayed as Imported: in the Page Setup drop-down list:


The alphanumeric sorting by file and layout names in the Batch Plot dialog has been improved. Now, even if the names of files or layouts contain numeric values, they are correctly sorted in ascending and descending order. For example, Layout10 will appear after Layout9 and before Layout11, and not between Layout1 and Layout2 as before.

Example of sorting a list by file name.
In this case, the names of layouts are displayed not in ascending or descending order, but in the order in which they are arranged in their files.


Example of sorting a list by layout name.
In this case, the file names are also arranged in ascending-descending order.


Now there is the possibility to turn off layer information when printing to PDF. The Include Layer Information option has been added to the Internal PDF Plotter Setup dialog. Its disabling can optimize further work with PDF files.


In the Import PDF (PDFIMPORT) dialog, the Remove duplicate objects option has been added, its disabling can speed up file import.


A new command MCLIPBYSELECTION creates a bounding prism taking the prior selection into account.


The command builds a bounding prism around the selected objects according to the size of their common overall rectangle.


You can edit the created prism with the MCLIP command.
With the new Face option, the UCS command allows you to view and align the UCS to any face of a 3D object. In this case, the Dynamic UCS mode (F6) should be enabled. The new UCS is displayed when you hover over a face.

image048.png image049.png
image050.png image051.png

 In the process of aligning and changing the coordinate system with the UCS command, there is a UCS preview icon near the cursor that allows you to visually evaluate the changed direction of the coordinate system axes.


In previous versions of nanoCAD, the dynamic UCS mode allowed specifying the UCS plane on the screen only once during the work of draw/edit command (when requesting the first vertex). Further queries and drawings were carried out in the same UCS, until the command completion.

Now, a new UCS plane can be specified during any next request for coordinates. To do this, in the process of specifying the vertex, you need to hold down the key combination CTRL+~.

To make the UCS dynamic setting mode work automatically with each request for coordinates without holding down the keys, you should assign the value 1 to the UCSDETECTMODE variable (default = 0).

The settings for rotating the model with the mouse wheel in the Options dialog have been redesigned and have become more understandable. You can disable or assign mouse wheel rotation (with or without SHIFT) and set the model’s rotation speed.
The rotation speed varies from 25% to 400% of the nominal value. The default value is 300%:


The Rotate the model with the mouse wheel checkbox allows you to disable the model rotation with the mouse wheel. If enabled, clicking the mouse wheel (with or without SHIFT) will be used to rotate the model with the Orbit command launched in transparent mode. If the setting is disabled, pressing the mouse wheel will not rotate the model. Only panning will be performed.


The Rotate model section allows you to select one of the usual ways for the user to control the orbit: by clicking on the mouse wheel or by pressing the mouse wheel while holding down the SHIFT key. Rotation will be performed only when the Rotate the model with the mouse wheel box is checked.


Now it has become possible to import large IFC files (1 GB or more).

In addition, when importing an IFC file, the IFC architectural objects are now automatically classified by layers.
In the Lengthening (LENGTHEN) command in the Dynamic mode, polylines are extended/shortened in one or both directions not only for the extreme segments, but for the entire polyline. The Dynamic mode is now also available for polylines with quadratic and cubic smoothing.
The Polyline object now has the possibility to select individual segments while holding down the CTRL key (or SHIFT+CTRL, depending on the selection mode).

The selected segments have functional grips that can be used to edit them.

image062.png image063.png

The selected segments can be moved, rotated and scaled with standard editing commands Move (MOVE), Rotate (ROTATE) and Scale (SCALE).

You can delete such segments, including internal ones, with the formation of remaining polyline objects.

The work of 3D snaps to spline of Knot and Vertex type.

The 3D Knot Snap finds fit points on a spline created by fit points.


The 3D Vertex Snap finds control vertices on a spline created from control vertices.


The new QNEW command is designed to create a document from the command line without having to switch to the non-dialog mode (FILEDIA=0).
A non-dialog variant of the command for extracting data (text) from attributes to a file -ATTEXT has been implemented for use in scripts.


The Copy Object Properties (MATCHPROP) command now has the possibility to copy layer property overrides in the viewport.
A button for the Select Group (PGROUP) command has been added to the interface. The button is located in the Group section of the Home tab of the ribbon interface and on the Group bar of the classic interface.

image069.png image070.png

The button switches the value of the PICKSTYLE variable to 0 or 1:

  • 0 – No group selection, the object included in the group is selected;
  • 1 – When you select an object in a group, all objects in the group are selected.
The display mode button of the Selection dialog has been moved to the status bar.


The Selection dialog opens when you click on objects that are very close to each other (or directly on top of each other) to specify which of them should be selected.


For developers of vertical applications, a mechanism for switching the content of the ribbon tab without using system variables has been implemented, similar to the mechanism for switching the content of the 3D Tools tab using the modeling mode buttons. You can describe such a switch and the content of each tab option using special commands. In the CFG file, you should use the ribbon tab content switching commands. The connection between the content and the switcher is configured by the ribbon_condition value in the ribbon tab description XML file, which is set in the CFG file by the set_ribbon_condition command by the keyword value specified in it.

XML Example: CFG Example:

<RibbonTabSource UID="ID_Org1" ribbon_condition="К1" Text="New tab" alias="text">

<RibbonPanelSourceReference PanelId="ID_switcher" ResizeStyle="Default">


<RibbonPanelSourceReference PanelId="ID_content1" ResizeStyle="Default">



CFG Example:

\configman\commands\Command-1] | weight=i1 | cmdtype=i1 | RealCommandName=sset_ribbon_condition | BitmapDll=snewbtns.dll | StatusText=s | TooltipText=s | LocalName=s | intername=s1 | keyword=sК1 | DispName=sFirst variant

The search for tools in the Customize User Interface (INTERFACE) dialog box has been improved. Commands are now proposed as you type in the search bar, similar to how command selection works in the command line.


The Map Underlay insertion (MAPVIEW) has been improved. Now it is possible to insert raster cartographic underlays By control points. When this option is selected, a dialog opens that allows you to specify the corresponding points in the drawing and on the raster.


Simultaneous insertion of multiple DWG files as xrefs has been implemented.

After running image075.png  DWG Reference command, select several DWG files in the dialog that opens holding down CTRL and SHIFT keys.


In the Internal Reference dialogue, configure the insertion parameters and click ОК.


The selected files will be inserted as external references with the specified parameters.


The external references selected in the External References dialog box are now automatically selected and highlighted in the drawing. Conversely, when selecting xref objects in a drawing, their names will automatically be selected in the External References dialog box. Single and multiple selection supported (using CTRL and SHIFT):


The new ERHIGHLIGHT system variable is responsible for highlighting objects in a drawing that are selected in the External References Manager. If the value is 0, only the names of references in the manager window are highlighted, if the value is 1, the corresponding objects in the drawing are highlighted.


In the External References dialog box, Reload All References and Select all commands have been added in the context menu:


The bug due to which some characters of the Indian alphabet were shifted in the blueprint has been fixed.


The bug due to which the Arabic letters “broke up” in a drawing and in the editor has been fixed. Now the characters remain merged, and the text is readable.
Now, when editing a multiline attribute (EATTEDIT), the display of the remaining block objects persists (both for the value of the variable ATTIPE=0, and for ATTIPE=1).

The bug due to which hiding the background of multiline text in Model space did not work in a user file has been fixed.

The Find and Replace command (FIND) has been improved. Now she not only finds, but also replaces text in multileaders.
The bug that caused the built-in PDF printer to not print a drawing viewport when it had positional leaders whose text crossed the viewport boundaries has been fixed.

The bug due to which a PDF file obtained after printing a user DWG file with a large number of entities by the internal PDF plotter was drawn slowly in the PDF viewer has been fixed.

The bug that in a particular case led to multiple duplication of objects in the drawing when importing a user PDF file has been fixed.

The bug and program slowdown caused by inserting multiple PDF files as an underlay in a user DWG file have been fixed.
The bug that in a particular case caused the multileader to shift in the user file after editing it has been fixed.

The bug that caused part of a large raster image not to be displayed in the drawing has been fixed.

The bug that caused applied dimensions to shift when entering the viewport of a user DWG file has been fixed.

The defects that in a particular case led to errors in displaying objects, dimensions and loss of associativity of dimensions in the user file have been fixed.
The bug in the behavior of the Quadrant object snap for a circle and an arc has been fixed. Now, if a circle or an arc was drawn in the UCS rotated relative to the WCS, the Quadrant snap will only work when they are in that UCS. At the same time, for an ellipse, the snap will work in both UCS and WCS.

The bug as a result of which, when drawing objects on the top face of a 3D solid using 2D snaps, unwanted snap to fit points of the bottom face occurred, has been fixed.
The corner reference point when drawing an arc in Center, start, corner mode. Now the countdown is from the point of specifying the beginning of the arc.

Switching edit modes of the Region object using the round grip now only happens for a specific object, even if there are several objects in the selection.

The bug that, in a particular case, led to impossibility to select objects in a user file using a crosshair, frame, or cutting box has been fixed.

The bug that caused the measurement scale to change when switching from a paper to a model in a user file has been fixed.
The bug that in a particular case led to the error The operation was not completed and the file was not created. Empty ACIS not allowed: (63) when trying to save a user STEP file.

The bug due to which files restored in version 20.1 stopped opening in another CAD program has been fixed. Files oversaved in version 23, 21.0 and 22.0 now open in another CAD program without recovery.

The bug that caused a multileader landing offset in a user file with UCS that was created in another CAD program has been fixed.

The bug of the FILLET command that made it impossible to set the cropping mode to zero radius has been fixed.

The default width of the Name and Status columns in the External References Manager has been increased.
An abnormal program termination when switching layouts if a non-current sheet was previously deleted programmatically has been fixed.

Incorrect work with the following printers has been fixed:

  • HP Designjet T770
  • Koniсa minolta bizhub C224e
  • HP Designjet T1100

The bug where between calls to the Plot command driver settings that did not depend on the options set in the Plot dialog were not saved for any external plotters has been fixed. Driver settings that do not depend on the options set in the Plot dialog are driver-specific settings. For example, type of paper (plain, photo, film), paper tray, toner save mode, etc.

Appearance of bold lines in Model space after assigning a plot style and checking the Display plot styles box in the Plot dialog has been fixed:

  • Draw a couple of lines in the model and open an existing file;
  • Open the Plot dialog and set any Plot style table;
  • Check the Display plot styles box;
  • Click Apply to layout and close the plot dialog;
  • Switch to any layout, return to the model.


Bug fixed: The HP DesignJet driver setup dialog appeared behind the nanoCAD window and was therefore not visible to a user.

The situation, when with the running progress indicators Check Printer Papers and Check Application Defined Papers, it was possible to uncheck/check boxes in the Plot dialog, call dialogs (for example, for creating layout options set, settings) has been fixed.


The Insert Layout from Template (LAYOUTFROMTEMPLATE) command has been fixed. Layouts were not created if there were proxy objects in the template.

The work of the non-dialog plotting command (-PLOT) has been fixed:

  • Plot settings were not saved when answering Yes to the prompt: Save changes to page setup? Or set shade plot quality?
  • The prompt Plot layout objects first? was processed incorrectly when printing a layout. In case of Yes answer, the Layout objects last option was set, though it should have been removed. In repeated printing, No reply was proposed by default instead of Yes.
  • The No value for the Display Plot Styles option did not work.

In the Plotter Properties dialog the Apply to layout button has been replaced to OK button, which better reflects the essence of the action and excludes the confusion with Apply to layout button in the Plot main dialog. The Plotter Properties dialog opens from the Plot dialog after opening an external plotter settings with its further completion by ОК.


In the preview window of the Plot dialog, text clipping at the size of the print margins has been fixed.


Incorrect display of paper format sizes in the print preview window for small formats has been fixed.


Import of faces and objects for a specific file has been fixed.

Import of a specific IFC4 file, which lost some objects: walls with window openings, has been fixed.
The isolate layer (LAYISO) command now saves its settings between work sessions.

The work of Match layer image088.png (LAYMCH) command has been restored.

The effect of the Apply layer filter to layer toolbar from the Layers dialog on the standard layer filter All non-Xref Layers has been restored.


The selection of an option value by symbol in the Properties bar and in the Ribbon has been restored.


  • Create several layers. For example: Blocks, Windows and Doors;
  • In the Properties bar or in the Ribbon, open the drop-down list of layers and press the letter d on the keyboard;
  • nanoCAD will highlight the Doors layer.


A number of errors when importing point clouds (NPC_IMPORT) from the RCP format, including those that caused the program to hang and crash when the file size is more than 2 GB have been fixed. Also RCS file checks have been added and the path generation function has been fixed.

The bug that in a particular case caused the program to stop working when trying to select a DWG table in a user file has been fixed.

The bug that in a particular case caused the program to stop working when trying to import a custom IFC file has been fixed.

The program crash when importing a custom PDF, or after pasting it as a background has been fixed.
An object associativity bug that led to an error message when changing dimension objects in a particular file.

A crash in the Construction and Mechanica modules when opening files has been fixed. The problem was in processing of proxy objects.

A crash when opening a file (problems with tessellation of polygonal faces) has been fixed.

A crash when opening a file (problems inside solid objects) has been fixed.

A crash when opening (problems with 3D) has been fixed.
The bug in the QSELECT dialog due to which multiline texts were erroneously taken into account in the text column has been fixed.

The bug due to which the settings of layer properties of design objects for new documents “flew off” has been fixed.

The bug due to which when switching from a layout to a model, the measurement scale of dimensions changes has been fixed.
The bug where nanoCAD installed under an administrator account would not run on other accounts has been fixed

The mechanism for updating XBim libraries when updating nanoCAD has been corrected.

The bug when, while creating startup configurations for loadable vertical applications, the encoding of Cyrillic paths in the #include lines was lost in the configuration master file, has been fixed.
Also the bug where the correct include link from the configuration file was not loaded if its encoding was saved in UTF8 format has been fixed.

A crash when calculating and displaying the length of some splines with a huge number of vertices, programmatically generated by the vertical application has been fixed. Also, a crash when trying to get the “Middle” anchor point for such splines and their “disappearance” when simplifying has been fixed. As a result of corrections, the mechanism for calculating the length of the spline has been redesigned.

The case when, after creating layouts according to a template on user files, and using the Audit (AUDIT) command, layouts disappeared in the document, and nanoCAD ended its work, has been fixed.

The bug due to which the viewport was not deleted in the model space of a custom file has been fixed.

The bug where the Convert to 2D (FLATTEN) command destroyed such SPDS proxy objects as Wall and Section, has been fixed

The bug due to which, while creating a polyline offset the width of its segments and the global width were not copied, has been fixed.


The error of copying a point cloud from one open document to another using COPY-PASTE commands has been fixed. The result was an incorrect cloud.

The bug due to which the LIST command for displaying data about the properties of selected objects incorrectly calculated the object area in some units (in particular, feet and inches) has been fixed.

The bug where the internal plotter settings dialog did not take into account the paper format previously selected in the plot settings dialog (opening with ISO A6 format displayed) has been fixed.

An erroneous behavior of the Open file location command of the context menu of the document tab, which resulted in opening the folder of the last opened file, has been fixed.

The bug due to which, in the dialogs for inserting xrefs and inserting blocks, objects on the preview were displayed without taking UCS into account.


It is forbidden to insert an external reference whose name matches the name of the file into which it is inserted. The following prompt appears on the command line: "Error: Possible circular reference to current drawing."

The error of inserting a nanoCAD drawing as an OLE object into other software products (for example, in Word or Excel) if the nanoCAD window was in a minimized state has been fixed.

Special paste of an object from nanoCAD into a third-party application as a Windows metafile (EMF) has been fixed:

  1. Copy the object from the nanoCAD drawing to the clipboard (CTRL+C).
  2. Paste into Word via Spec Paste (CTRL+ALT+V) and select the Windows Metafile (EMF) type.
The bug due to which, when copying objects the position of the dimension line of the diameter dimension was changed, and one of the arrows of the dimension lines was also lost, has been fixed.


The error in constructing a radius dimension when creating a connection, when only an arrow was displayed without a dimension line.

The delay in changing the font and style in the drop-down list of the multiline text editor after the undo operation (UNDO) has been fixed:

  • When editing multiline text, select the text and select a different font in the Font field (for ex-ample, Arial) or set a different style in the Style field.
  • Undo the last action (UNDO).
The text shape will change, but the name of the font (or style) in the field on the panel will remain the same.


The multiline text bug due to which, in a particular case, the TTF font was not changed has been fixed.

The bug where pressing Enter at the end of the last line of a multiline text while editing it caused the MTEDIT command to exit instead of creating another line.

The bug in the single line text creation command has been fixed. When trying to change the location of the next text object by clicking in the drawing field, the command crashed.


The error in the display order of raster images after aligning the underlying raster with the ALIGN command has been fixed. After applying the command to a raster image, it was displayed above other images, until the viewport was updated (REGEN).



The bug, as a result of which, in some drawings, the document purge command from the command line (-PURGE) with the Full option led to the program crash (the Standard table style was deleted) has been fixed.

A defect in changing the UCS in a user file has been fixed.

The non-working button and the menu item of the command to insert the material were blocked in the table editor and the notebook of nanoCAD, since it is possible to insert a material only with the active Construction and Mechanica modules.


Now, when selecting objects, the state of the PICKFIRST variable is taken into account. The description of the variable in the System Variables Monitor has also been edited.
When inserting a nanoCAD drawing file into another program (for example, Word) as an OLE-object, the error message “Unable to create an object. Make sure this application is registered in the system” appeared. This happened when nanoCAD was minimized. This error has been fixed.

Two bugs have been fixed, which appeared after the document window was made floating:

  1. Open two documents.
  2. Make one of the documents floating (Float window item of the document tab context menu).
  3. Create a new block in the floating document.
  4. Close the second document.
  5. When calling the block editing (BEDIT) or reference editing (REFEDIT) commands in a floating document, the tabs of these editors did not appear in the ribbon.

  1. In a document with a block, run commands for editing a block or an external reference (BEDIT or REFEDIT);
  2. Undock the document window;
  3. Close the editor in the floating window with the appropriate command on the editor bar.
  4. 4In the main window, the editor tab remains hanging, and it is impossible to close it.

Syntax errors in the configuration (CFG) files leading to errors have been fixed.
The interface customization dialog (Customize User Interface (INTERFACE command)) became more resistant to syntax errors in configuration files. For example, the dialog would break if a FlyOutStart=0 was encountered in the CFG file without a preceding FlyOutStart=1. In particular, the keyboard shortcuts section turned out to be empty.
If an attempt was made to create a new key combination with an empty list of keyboard shortcuts, then the program crashed.

The icons and design of the Welcome window have been optimized to work with 4K monitors. Tooltips to window elements have been added.

The COGOPoint Styles section in the Drawing Explorer bar has been renamed to COGOPoints. The User-Defined Property Classification has been added to the section.


2D polyline snaps were displayed in the wrong place. The error could be stably reproduced on a 2D polyline obtained by creating an ellipse with PELLIPSE = 1.


When opening the Find and Replace dialog box (Ctrl+F), the cursor is immediately placed in the Find what field. No extra click needed to get to this dialog like before.


 A lisp file interpretation error has been fixed: setting a custom viewport scale resulted in an error.

In nanoCAD the processing of multiple imposed and inserted circular references. Where, for example, some DWG files can have superimposed links to other DWGs in which they themselves are inserted as a reference.


In previous versions of nanoCAD, it was impossible to create or edit an existing system of cyclic references - once such a reference was deleted, it either could not be reconnected (there was an error Possible circular reference to current drawing), or it was necessary to break the links for each file.

The bug when, while editing an existing text in a DWG table cell (DTABLE command), the text being entered was simultaneously displayed above the previously entered text, has been fixed.


The bug when while editing an existing text in a DWG table cell (DTABLE command) it was impossible to delete this text - after editing the cell, the text was displayed again.

The deletion of the original object when creating a cloud by object has been restored:

  1. Create a rectangle.
  2. Run the Revision cloud (REVCLOUD) command, select the Object command option, specify a rectangle.

The cloud will be created and the rectangle will be deleted.


A situation with the program crash when inserting an associative array added earlier to the Tool Palettes Manager bar:

  1. Add any associative array to the Tool Palettes Manager bar by dragging. It will get a name like *U2.
  2. When trying to insert an array into another drawing, the program crashed.

Now it is prohibited to add an anonymous block insertions to the Tool Palettes Manager bar (which happens in the case of an associative array)

The crash when enabling and disabling a layer with a dot in its name in the Properties bar has been fixed.

  1. Create a layer in a new file. The title should contain a dot at the end. For example: “Layer1.”
  2. In the Properties bar, turn off visibility of this layer, or freeze, or block, or turn on/off plotting. Abnormal program termination.

A critical API error related to deleting a drawing object from a parallel stream when a box selection command is active has been fixed.

The nanoCAD crash when updating the cache of paper formats when accessed through a script has been fixed.
If there is a connection to a database, the Importing Cloud Data from a Database (DB_TO_NPC) command loads a point cloud from the specified database into the drawing. If there is no connection to the database, you will be prompted to configure it.
When exporting a point cloud from a database, it is possible to display a point cloud preview in the import dialog, and configure the import parameters.

If there is a connection to a database, the Exporting Cloud Data to a Database (NPC_TO_DB) command uploads a point cloud from the drawing to the specified database. If there is no connection to the database, you will be prompted to configure it.

The Database Configuration (NPC_DB_CONFIG) command connects to databases with point clouds.


The commands to manage the display of features apply to point clouds in which geometric features have been previously found: pipelines, pipeline elements, planes, and plane elements.



  • Hide Feature (NPC_HIDE_FEATURE). The command hides the feature specified in the point cloud (pipeline element, plane). Works with point clouds in which geometric features have previously been recognized.
  • Hide All Features (NPC_HIDE_ALL_FEATURES). The command hides all features found in the point cloud (pipeline elements, planes). Works with point clouds in which geometric features have previously been recognized. Points where features have not been identified remain visible.
  • Isolate Feature (NPC_ISOLATE_FEATURE). The command isolates the feature specified in the point cloud (pipeline element, plane). All other cloud points are hidden. Works with point clouds in which geometric features have previously been recognized.
  • Isolate All features (NPC_ISOLATE_ALL_FEATURES). The command isolates all features found in the point cloud (pipeline elements, planes). Works with point clouds in which geometric features have previously been recognized. Points where features have not been identified are hidden.
  • Feature Isolation Reset (NPC_UNISOLATE_ALL_FEATURES). The command turns on the display of all isolated features, as well as points where features have not been identified.
  • Show All Features (NPC_SHOW_ALL_FEATURES). The command displays all features, while the points where features have not been identified remain invisible (if they were previously hidden).
The Determining the Radius (_NPC_RADIUS) command copies the radius of pipes and cylinders found in the point cloud to the command line.


The Determining the Diameter (_NPC_DIAMETER) command copies the diameter of pipes and cylinders found in the point cloud to the command line.


The dialog box of the Import point cloud (NPC_IMPORT) command has been completely updated, new functionality has been added.


  • A possibility of simultaneous import of several files has appeared;
  • Viewing information about the file has been added;
  • Now it is possible to transform a cloud by EPSG codes, if the point cloud has a coordinate system described by the EPSG code;
  • A possibility to set any cloud coordinate system from the list of EPSG codes, even if initially it was not linked to the cloud has been added;
  • The point cloud preview window has acquired convenient tools for navigating the cloud, including in 3D viewing mode;
  • The function of splitting a cloud into blocks, both along the mesh and along the flight line, has been implemented. In this case, the cloud is not loaded immediately into the drawing. A set of dwg files is created in the folder with the point cloud, each of which contains a block – a fragment of the cloud obtained by splitting the source file in accordance with the specified parameters. The function is convenient to use to automate import, the resulting fragments can be loaded into the drawing separately, significantly reducing the amount of memory used.


Point cloud clipping commands are divided into inverting and non-inverting. Now, when clipping point clouds, you no longer need to select the option to clip points Inside or Outside. There are now separate commands for clipping inside and outside.


In the process of drawing, it has become possible to snap to the turning point of the pipeline.

Version 22

Now a document window (drawing file tab) can be detached from the nanoCAD Platform window by making it a float window using the image002.png Float Window (FLOAT_WINDOW) command.


The command can be called from the context menu of the document tab or from the command line.

As a result, the document tab will be undocked from the platform window as a floating window.


The floating document window is always in the foreground. It does not contain a command line, it cannot contain document tabs. You cannot attach functional bers to it.

In the Options dialog you can specify: whether the floating window should contain a ribbon, a menu, and a status bar.


You can attach a floating document window back to the main platform window as a tab using the image002.png Dock Window (DOCK_WINDOW) button on the right side of the window title bar.


3D snaps for solid objects (objects of the 3D Solid type) have become available. Their setting is separate from 3D snaps to recognized point cloud geometry in the Drafting Settings dialog box and the context menu.


The functionality has been added for creating and editing a new type of associative (dynamic) arrays – Array by Path. Previously, such arrays were perceived as blocks.


The Array by Path (ARRAYPATH) command allows you to evenly distribute the object copies along a path or a part of it. The path can be a line, polyline, 3D polyline, spline, helix, arc, circle, or ellipse.

image010.png     image011.png


The Array toolbar appeared in the classic interface.


The Editing an Array (ARRAYEDIT) command allows you to edit the source of an associative array in place. It became possible to modify existing associative arrays by editing their specific parameters and source objects.



The error that occurred when changing the base point in building an associative array has been fixed. As a result, the array elements were shifted relative to the specified point instead of the base point.

image016.png   image017.png

The mechanism for creating and managing a view bounding prism (MCLIP) has been completely redesigned and optimized. Prism usage has become easy and intuitive.


The prism can be stretched, compressed, and modified by dragging any edges and faces in any place. In this case, it changes its appearance in accordance with the user's expectations.

Thus, you can grab any area of the visible face and move it along its normal (in the case of a rectangular prism) or in any direction (in the case of a polygonal one). Snaps and orthogonal drawing modes can be used. Hidden faces can be moved by grabbing one of their edges. The entire prism can be dragged while holding CTRL.


At the moment of creating or editing a prism, it is displayed in all viewports, however, its effect extends only to the screen in which it was created or was selected for editing. When the prism is set up, it will crop the image only in the viewport for which it was created.


To create a new or edit an existing prism, go to the desired viewport and run the Bounding Prism command.

While editing a prism, you can switch to another viewport to continue editing it from a more convenient angle. In this case, in the new viewport, editing will continue on the prism that belongs to the previous viewport (in which the Bounding Prism command was run), and not to the current one. A prism in its own viewport is displayed brighter than in others, so that it is always clear which viewport it belongs to, no matter which viewport is currently active.


The Drawing Explorer bar has been updated.
The following filters have been added:
  • image022.png Show visible objects;
  • image023.png Show invisible objects.

Standard blocks, 3D blocks and dynamic blocks are now displayed separately.
Multiline styles are displayed.


Such Topoplan objects appeared as groups of points of coordinate geometry, as well as sets of styles of point markers and styles of their labels.


The styles of labels and markers of coordinate geometry are edited by selecting the desired style in the drawing explorer and then calling the command from the context menu. The properties of the selected style are displayed and changed in the Properties bar.

Materials according to EN, DIN and ASTM with the possibility of their designation both by chemical composition or brand, and by numbers.
The updated Spell Check bar, in addition to improving ergonomics, provides a new functionality.
Now it is possible to check text objects of a drawing for spelling mistakes not only on demand, but also in real time. All new and modified objects will be checked for spelling. If mistakes are found, the words will be underlined in the drawing field and added to the list of found mistakes in the bar.
In this case the bar allows you to work with several documents at the same time without losing the results of spell check of the previous document when switching to the next document.

image026.png   image027.png

In the spell check settings you can:
  • Add or exclude particular types of objects from the check.
  • Exclude certain types of text from the check.
  • Instruct the spell check command to run on a separate thread to process information independent of the platform thread.


3D thread on standard fasteners.


Now the version of the image029.png Purge Document command to work from the command line (-PURGE) allows you to clear the object sorting table. The sort table contains lists of object order (DRAWORDER).


Sometimes there are so many such records that the program starts working with the document much more slowly. Cleaning the table removes empty records, greatly speeding up the work.


Now, when opening documents, the need to purge annotative scales and empty entries in the object sorting table is checked. Depending on the check result, the following prompts may be displayed in the command line:
  • Attention: the file contains a large number of annotative scales (number). It is recommended to remove the scales by running the -PURGE command and selecting the ANnotscales option.
  • Attention: the file contains a large number of empty entries in the sort table (number). It is recommended to remove them by running the -PURGE command and selecting the sorTTable option.
To speed up the opening of files, multi-threaded loading of DWG files has been implemented. The multithreading mode is controlled by the MTMODE system variable. A program interface has been opened that allows application developers to use multithreading to load objects, which gives a significant gain, including when opening files with a large number of specialized objects.
Import Point Clouds (NPC_IMPORT)
  • The import of clouds in the LAZ format (LAS zipped format) has appeared.
  • Recalculation of coordinates during import was supplemented by GCS 2011 geosystem.
  • A new dialog has appeared that shows extended information about the parameters of the imported file.


  • The Point Cloud object received two geoparameters. When recalculated, the cloud is marked with the geo-coordinate system to which it was recalculated.


  • Support for EPSG geotagging.
  • Unlimited set of coordinate geosystems (the list can be supplemented with your own CS). Possibility of more complete control of recalculation parameters: to which CS and with what parameters to recalculate.
  • Improved import of point clouds from PTS format. It became possible to import such clouds with intensity in the ranges [-2048..2048], [0..255] and [0..65535], and not only [-4096..4096] as it was before.
  • Import of normals from PTS format has been fixed.
Export Point Clouds (NPC_EXPORT)
The PTS format has been added to the export command.
New coordinate recalculation commands have appeared that allow you to recalculate the coordinates of already loaded point clouds. This creates a new cloud for the desired coordinate system.


  • image035.png NPC_REPROJECTION – recalculation of coordinates of a point cloud with settings from GCSTrans.xml file;


  • image037.png NPC_EPSG_REPROJECTION – recalculation of a point cloud coordinates by EPSG codes.


These commands are mutually exclusive: you can use either one or the other.

Point Cloud Information (NPC_INFO)
The dialog interface has been completely redesigned. Individual interactive charts are opened by clicking the image039.png button next to the corresponding parameter.






New features have appeared:

  • Clipping history. If the clip and section commands were applied to the point cloud, you can see the full list.

  • Information about the geosystem coordinates of the point cloud. If the cloud coordinates were recalculated during import, it is possible to view its parameters.

image046.png  image048.jpg

The clipping history displays all cloud clipping manipulations with their attributes. The initial state of the cloud is displayed at the top of the list. When you select a clipping state from the list, all subsequent clippings become inactive for the point cloud.

Version 21

nanoCAD has a new set of tools to assist you making drawings with isometric projection. Isometric drawings simulate three-dimensional views of objects from one viewpoint.
To create isometric drawings, it is convenient to use the Isometry toolbar.

It contains:

  • The button to enable the isometric drawing mode;

  • Three buttons to set isometric planes (ISODRAFT1, ISODRAFT2 and ISODRAFT3 commands or an option on ISODRAFT command);

  • Buttons to create isorectangles, isocircles and isoarcs (rectangles, circles and arcs in an isometric projection).

Isometric drafting mode

For isometric drawing, use the Isometric drafting mode. The mode is enabled by entering the ISODRAFT command, by  button on the Isometry toolbar or by  button in the status bar.


The isometry mode allows for quick switch between three isometric planes (isoplanes) by F5 key or by clicking an appropriate button on the Isometry bar.

  •  Isoplane Left. The plane allows you to create objects oriented along the axes of 90 and 150 degrees.

  •  Isoplane Right. The plane allows you to create objects oriented along axes of 30 and 90 degrees.

  •  Isoplane Top. The plane allows you to create objects oriented along the axes of 30 and 150 degrees.

Isometric Mode’s Impact on Drawing Settings

When you enable isometric drafting mode, nanoCAD automatically changes the following settings to match the selected isoplane:

  • Orthogonal direction

  • Snap orientation

  • Grid orientation

  • Polar tracking angles

  • Orientation of isometric circles, arcs, and rectangles as they are created

Creating Isometric Objects

The following commands are used to create circles, arcs, rectangles in the current isometric plane:

  • To create a circle in the current plane, use  ISOCIRCLE command that starts the ELLIPSE command with the Isocircle option;

  • To create a rectangle in the current plane, use  ISORECTANGLE command that starts the RECTANGLE command with the Isorectangle option;

  • To create an elliptical arc in the current isometric plane, use  ISOARC command that starts creating an elliptical arc by the ELLIPSE with the Arc > Isoarc option.

Related System Variables

The SNAPSTYL system variable allows you to change the drawing mode. The variable values are integers.

The SNAPISOPAIR system variable allows you to change the current isometric plane in the current viewport. The variable values are integers.

nanoCAD 21 redesigns the commands you used to construct rectangular and circular arrays. 

The commands now work interactively, without needing a dialog box.

As well, nanoCAD now creates associative arrays. The objects that make up an associative array are stored as a single array object. The Array - Associativity system variable toggles arrays between associative and non-associative. Associative arrays allow you to change the number of objects and the distances between them through grips on the array or with the Properties panel.

Now it became possible to:

  • add remove and modify block objects while maintaining the integrity of dynamic block parameters. Actions concern objects that are not involved in the block parameterization;
  • convert any block to dynamic;
  • replace the insertion point.
Most of these features are available in the block editing mode by the Block editor command (BEDIT).

New Block Base Point Relocation 

The base point of blocks can be relocated with the  BBASEPT command. The base point locates the insertion point of blocks, and the position of the grip.

Reset block

Editing dynamic block inserts and then re-editing this block definition may distort the appearance of its inserts. The    Reset block (RESETBLOCK) command resets the parameters of the selected dynamic block inserts to default values. It is opened from the context menu of the selected inserts or from the command line.

Now there is a possibility to transfer and save user interface configuration. To transfer settings between versions or from one computer to another, use two commands: Import UI (UIIMPORT) and Export UI (UIEXPORT).

The Export UI command allows you to save a package of individual configuration, while the Import UI command applies it to the current version of the program.

Export UI allows you to save both the composition of interface elements (ribbon, toolbars, etc.), configured in the Customize user interface dialogue box, and the display with location of interface elements (location of toolbars, palettes, command line, visual style of interface, way of the ribbon display, size and location of the program window).

Thus, you can quickly and easily transfer user configurations for convenient work with the program, as well as save the configurations package to prevent them from being lost.

If necessary, you can also edit LSP-file, which describes Import UI and Export UI, commands and edit the list of file formats included in the configuration package being exported.

Redesigned Field Dialog Box

The FIELD command’s dialog box is redesigned:

Additional format dialogue

More detailed formatting of numeric values is now available in the field editor. The Additional format button opens the dialogue box, where you can set the conversion factor, zero suppression, additional text, numeric separator.

Option for fields inside a block

Display value for block reference – the checkbox is displayed only for object properties fields that are located inside the block. For example, when editing a field inside a block attribute definition.

The parameter obliges the property to calculate its value relative to the size and orientation of the block reference in the drawing, and not relative to the internal block description space. So, for example, the coordinates of the center of the object included in the block will be calculated relative to the drawing coordinate system, and not relative to the coordinates of the block definition.

Commands to Work with Groups

Commands for working with groups now have their own place on the ribbon (Group section of the Main tab) and Group toolbar. This makes it more convenient to carry out grouping and ungrouping outside of the Object Grouping dialog box, and allows you to create unnamed groups.

   New group (GROUP)

A new command to create a group of objects. Unlike the New option, the GROUP command allows you to create both name and unnamed group.

   Exploding a group (UNGROUP)

Exploding a group or ungrouping.

   Editing a group (GROUPEDIT)

Adding or deleting objects from a group.

   Dialogue for creating groups (CLASSICGROUP)

Displays the Object grouping dialogue box to manage groups. In the previous program versions this dialogue box was called by the Group command (GROUP).

nanoCAD offers a new way to recover drawings accidently lost when exiting drawings without saving, such as when closing all open drawings at once. In other cases, objects are erased from drawings, and then the drawings are saved and closed, after which the undo/redo mechanism no longer works.

The new rescue mechanism restores them from a temporary storage, and is enabled in the Options dialogue box: Save documents section > File History.

  • Save file history (FILEHISTORY variable) – determines whether the auto-save history is enabled (0 – disabled or 1 – enabled)

  • Number of stored file versions (FILEHISTORYMAX variable) – determines the maximum number of auto-saved version of each drawing file, up to 32767 versions.

  • File versions are stored for <15> days (FILEHISTORYDURATION variable) – determines the duration to store each auto-saved file, up to 32767 days (approximately 90 years).

  • File history folder – specifies the folder in which to store auto-saved files

The Open file history command (OPENHISTORY) opens files from the archive storage.

The earliest files are deleted from storage automatically once the number of archive files specified by FILEHISTORYMAX is reached. When closing nanoCAD, the storage period for files in the archive is checked, and files with a life of longer than FILEHISTORYDURATION are deleted automatically.

nanoCAD inserts underlays from a number of cartographic services in a variety of formats:

  • Vector maps from OpenStreetMap

  • Raster maps from ArcGis, Microsoft Bing, Google Maps, MapBox, OpenStreetMaps, OSM Topo, and Yandex Maps

  • For some providers, additions map types are supported, such as streets, satellite, hybrid, relief, and topographic

Three-dimensional terrain models can also be placed as overlays.

Improved Import and Export

  • Added import and export of clouds files in E57 and ReCAP (*.rcs) formats
  • Improved algorithm for importing cropped volumes
  • Drag and drop nanoCAD point cloud files (*.npc) into drawings
  • Set drawing measurement units in the Import dialog box
  • Export point clouds in 3D PDF format

New Commands for Clipping Clouds

  • Added commands for clipping cloud by sphere and cylinder shapes
  • Improved clipping command interface
  • New command to invert point cloud clipping boundaries

3D Geometric Snaps

The following three-dimensional snaps recognize geometry in point clouds. They are turned on and off through the Drafting Settings dialog box or at the status bar:
  • Point Cloud Edge Node
  • Point Cloud Edge Nearest
  • Point Cloud Edge Perpendicular
  • Point Cloud Plane Nearest
  • Point Cloud Plane Perpendicular
  • Point Cloud Feature Surface
  • Point Cloud Feature Axe Node
  • Point Cloud Feature Axe
  • Point Cloud Feature Center

The Windows properties associated with nanoCAD now open drawing files with the name of a sheet or a view. A drawing within a sheet set is opened with the new -list switch:
<path>/ncad.exe [<path>/drawing_file] [-list "sheet name"]
The named view saved in a drawing is displayed upon opening the drawing with the new -v switch:
<path>/ncad.exe [<path>/drawing_file] [-v "view name"]
 Either the - or the / character can be used for the switch.

Copy OLE-link Command

The new Copy OLE-link (COPYLINK) command copies the current view to the clipboard so that it can be linked in other OLE-aware applications. An object of nanoCAD drawing type is created in the other program. This means you can insert nanoCAD drawings into Word documents as OLE objects, which can then be edited in nanoCAD by just a double-click.

Renamed OLE Commands

The names of OLE- related commands are changed to be more intuitive in the toolbar/menu interface:

In the Insert menu, the Object… item becomes OLE-Object…. (The ellipsis indicates a dialog box will be opened.)

In the Edit menu, the following items are renamed:

  • Copy view becomes Copy OLE-link

  • Links… becomes OLE-links

  • Update all links becomes Update all OLE-links

OLE in the Properties Panel

Properties are added to the Properties panel for OLE objects.

With the Locator tool, you can now interactively rotate the view of a model:

  • While holding down the Alt key, and then select any point on the locator circle
  • Choosing one of the four marked points to rotate a view by 90◦.

The arrow points to the new view rotation position.

Arc Direction by Cursor Movement

nanoCAD now draws arcs (including elliptical ones) in the direction that the cursor moves. This applies to the following arc construction methods:

  • Center-Start-End

  • Start-Center-End

  • Elliptical arcs

You can also change the direction for constructing arcs by holding down the Ctrl key.

Circle by Three Tangents

Circles can now be drawn tangent to three other objects (menu Draw > Circle).


Circles Tangent to Splines and Ellipses

Now the command to create a circle by tangent, tangent and radius, allows you to specify splines, ellipses and elliptical arcs as tangents. As well, creating circles tangent to arcs or other circles is improved.

Breaking Ellipses and Closed Polylines by Two Points

When breaking an ellipse or a closed polyline with two points, the sequence of picking points determines which part of the objects to remove. (Previously, the same part always remained, regardless of the pick order.)

Lengthening in Both Directions

Lengthen (LENGTHEN) command now lengthens open objects symmetrically in both directions, through a new switch Two sides/One side. This is useful, for instance, for increasing the lengths of centerlines in both directions.

Editing Spline Fit Points with Ctrl

Spline fit points can now be edited by holding down the Ctrl key while clicking on a grip, just as with polylines. The context menu is updated to reflect this.

New Lasso Object Selection

Objects can now be selected using the lasso method: while holding down the left mouse button, move the cursor around objects. Objects are selected by a lasso or a rectangular selection frame, depending on your actions:

  • Move the cursor in the drawing area while holding down the left mouse button, the lasso outline is drawn. To end the selection, release the mouse button.

  • A single click in an empty area of the drawing starts a rectangular selection window. To complete the selection, click a second point.

The direction of cursor movement determines which objects are selected:

  • Move the cursor to the right, and objects entirely inside the area are selected. The selection area (window or lasso) is shown with a blue semi-transparent fill. 

  • Move the cursor to the left, and objects inside and crossing the boundary are selected. The selection area (window or lasso) is shown with a green semi-transparent fill. 

While selecting objects by the lasso method, you can cycle through three lasso modes by pressing the Space key: 

  • Select only objects completely inside the lasso area

  • Select all objects inside and crossing the lasso

  • Select only objects crossing the lasso line



Selection Preview Filter

Three more objects types are added to the Selection Preview Filter dialog box: Group, Mesh, and Polyface Mesh.

Interactive Actions with the Right Mouse Button

When you drag-and-drop objects while holding down the right mouse button, a shortcut menu appears with additional actions: Move here, Copy here, Paste as block. Select one to perform the action.

Multiple Copies with Ctrl

While moving, rotating, scaling, or mirroring objects with grips, hold down the Ctrl key to create copies:

  • Select one or more objects

  • Click on a grip

  • Press the Spacebar to switch between copy, rotate, scale, or mirror actions

  • Hold down Ctrl, and then click to locate copies of the selected objects

Enhanced Rotate Command

The ROTATE command gains the Key point option. It combines the base point with the reference angle. When you specify a reference angle, the first point you pick for the angle is the base point, about which rotation takes place.

Isolation/Unisolate History

Two new undo/redo functions let you navigate through the sequence of isolation steps: Undo the isolation step and Redo the isolation step. Isolation and its undo are independent of the general undo-redo mechanism, so you can isolate a set of objects, edit them, and then return the isolation to a previous visibility state. Changes to the edited objects are unaffected by undoing the isolation history.

Grouping Undo/Redo 

The new BEgin and End options in the Undo and Redo commands (UNDO, REDO) combine a sequence of actions to be reversed in a single step. Those commands performed after setting BEgin and before setting the End option are undone simultaneously. You can create multiple BEgin and End sets, each of which are reversed in sequence.

1. After setting the BEgin option, the Begin of command group item appears in the command list.

2. Following this, any commands you execute are added in the undo list of operations, one by one.

3. Until the End option is applied, the commands still can be cancelled by one, right up to the Begin of command group item.
4. Once the End option is applied, all actions in the undo list between the beginning and the end collapse into a single group of undoable commands.

5. At this point, these commands can only be reversed together.


When previously you copied properties to large numbers of objects with the MATCHPROP command, you may have accidentally copied them to a wrong object. In this case, you had to cancel the command and start copying properties anew.

To avoid this problem, a local undo option is added to the MATCHPROP command. The option appears when you specify the Select destination object(s) prompt.

Polar Spacing

The new Polar Spacing option specifies the spacing distance during polar snap, if the Polar snap (POLARDIST system variable) is turned on. When Polar Distance is set to zero, the polar spacing is equal to the Snap X spacing. Polar spacing is effective works when polar or object tracking modes are enabled.

New Snap Types

  • Grid snap – sets the snap as a rectangular grid with spacing specified by Grid Spacing

- Rectangular Snap – sets rectangular as the snap style and deactivate isometric drawing mode
- Isometric Snap – sets isometric as the snap style and activates the isometric drawing mode

  • Polar – sets the snap as a polar array. With polar snap and polar tracking enabled, the cursor snaps to tracking lines from the base point at angles specified on the Polar Tracking tab.
To use polar snap type in the isometric drawing mode:

  1. Turn on Grid snap

  2. Set the grid to isometric snap

  3. Switch to Polar snap

Polar spacing

Manages the spacing distance of the polar snap.

Spacing – polar snap spacing. Becomes available, if the Polar snap (POLARDIST system variable) is set. In case of zero value, the polar spacing is equal to the snap spacing interval by X. Works when polar or object tracking mode is enabled.

Follow Dynamic UCS

The new Follow dynamic UCS setting orients the grid plane to match the XY plane of dynamic UCS automatically (GRIDDISPLAY system variable).

Now you can set object snaps temporarily. To do this, enter a snap keyword during a command when you are prompted for a point, and then press Enter. The snap is set temporarily. 


The full list of object snap keywords is available by typing OS_ at the command prompt, or from the status bar.

The list of object snap keywords is given by the table:


      Snap type


      Tracking point




     Mid between two points








     Apparent intersection


     Line extension












     Insertion point






     Disabling object snap

A new option Replace Z Value with Current Elevation works with for object snaps in 3D space. When enabled, it snaps to points on the XY plane in the current UCS. 

The figure below shows two 3D polylines drawn object-snapped to the vertices of a mesh. The polyline in red uses the normal object snap modes; the one in blue with the Z-coordinate replacement option enabled.


In this mode, the Z coordinate value is replaced with one of the following:

  • The value of its projection to XY plane

  • The value of its projection to a plane parallel to the XY plane at the level specified by the ELEVATION variable, if it is non-zero).

Change the value of the ELEVATION variable to have the points snap at a specific distance above (positive values) or below (negative values) the XY plane. 

The option is enabled in the Snap settings section of the Options dialog box, and is synchronized with the OSNAPZ variable.

Fields are added for entering the increment of length and angle when editing objects by grips;

Support is added for the DYNDIVIS variable when editing objects by grips;

Not all dynamic dimensions can be seen on the screen simultaneously. The number of simultaneously displayed dimensions is controlled by the DYNDIVIS variable. Depending on its value, the following can be displayed simultaneously:

  • Only one dimension (DYNDIVIS = 0)

  • Only two dimensions (= 1)

  • or all dimensions (= 2)

If only one or two dimensions are displayed simultaneously, and you need to display others, this can be done by cyclically pressing the Tab key. Press Tab until the desired dimensions are visible. On subsequent cursor movement, the selected dimensions will continue to be displayed.


Dynamic input is enhanced through the following additions:

  • Input length and angle increment fields appear when editing objects with grips

  • Dynamic input implemented for ellipse creation

  • Dynamic input fields appear for the second and the next points when drawing a variety of objects in UCS

  • Input and editing of dynamic dimensions for 3D polylines in UCS

  • DYNDIVIS variable added for editing objects with grips

  • Bugs while using dynamic input while constructing lines and circles are corrected

Using hyphen in bulleted lists

Now you can create bulleted lists using dashes.

Aligning the last line

When you add a Tab to the end of the last line of distributed multiline text, then it is aligned to the left and remains so after editing is completed.

Blocking subdimensional text

Now the cleared Dimensions box in the Main options tab of the Design Settings dialogue box (Section Edit > by double-click) also blocks editing by double-click and subdimensional multiline text.

Hiding the text background for different type objects

To hide background for multiline text, multiline attributes and multileader multiline text use a separate command  on the ribbon.

Objects can be selected before or after the command is performed. This allows you to apply the command to several selected different type of objects.

The command displays the Background mask dialogue box, which will display parameters for hiding background for multiline text in the first selected object.

When switching the text type of the Default value from multiline text to single-line text in the Attribute definition dialog box (ATTDEF command), a warning is now issued when the text is so long that it would be truncated. Previously, the text was completely erased.

When switching from a single-line attribute to a multiline one, the text is also preserved.

The following bugs in multileaders are corrected:

  • If a TTF font was used, then spaces were not underlined

  • Text was incorrectly underlined in multileaders with Bottom or Top attachment and Underline and Middle justification

  • Text in multileaders with Top attachment had its Left alignment changed to Right

The Modify > Multileader menu gains multileader editing commands:

For dimensions and multileaders created in other CAD systems, associativity with objects is maintained when they are imported into nanoCAD.

The associative links of dimensions with objects can be broken by shifting the grips of extension lines.

The Break dimension command (DIMBREAK) is renamed MDIMBREAK.

The Restore dimension command (DIMUNBREAK) is renamed MDIMUNBREAK.

A new version of the Break and restore dimension command (DIMBREAK) combines the functions of both commands.

Sheet lists can now be generated from sheet set as a table. From the Sheet Set toolbar, select the name of a sheet set and sheet group, then from the context menu select the Insert Sheet list item.

Templates provided for sheet sets contain the required settings. To change the style of the sheet list, edit the table style with the table style dialog box (TABLESTYLE command).

You can now select multiple sheets by holding down the Ctrl or Shift buttons in the Batch Plot dialog box (PUBLISH command). Use Ctrl to select individual sheets, and/or Shift to select ranges of sheets.

As well, you can directly select a different page setup for each sheet from the drop-down list of the Page setup option.

The Rename layout command no longer requires you to re-enter a layout name when renaming it. The name can be changed directly in the tab. As well, you can reorder the list of layout tabs by drag and drop.

The Step left and Step right buttons were removed from the layout tab’s context menu as being unnecessary.
The new  Viewport align (ALIGNSPACE) command adjusts the pan and zoom factor of objects in layout viewports based on an alignment point in model and paper space. Points specified in model space are aligned to the points set in paper space.

  • Specifying a point in model space and another point in paper space offsets (pans) the view

  • Specifying two points in model space and two in paper space sets zoom scaling, panning, and rotation. The zoom factor and UCS rotation are adjusted according to the points specified.

The context menu for paper space viewports has been expanded:

Now when importing PDF files using the Import PDF (PDFIMPORT) command, text data are placed on the same layers, on which they were when creating a PDF file. Names of layers will start with PDF prefix. For this, in the Import PDF dialogue box, when selecting layers parameters, select the Use PDF layers option;

Solid fills in nanoCAD Platform are now imported by a fill, and not as a contour as before;

A bug with importing gradient fills from PDF, when some types of gradient fills were not imported into the drawing has been fixed. Gradient fills are imported as raster images.

PNG files can now have transparent backgrounds through the use of the alpha channel.

The new Transparency command (TRANSPARENCY) controls the transparency of background pixels in raster images. The command is available from the ribbon (Visualization group), the Raster menu, and the Raster toolbar.

Now, when opening files containing .dwg tables created in other CAD systems, the values in cells with formulas are recalculated and displayed correctly.

You can optimize the work in the program when connecting to a workstation remotely via RDP by using the enhanced DirectX compatibility mode in the Options dialogue.

If the box is checked, DirectX 9 is used. When cleared, the default DirectX version is used. In most cases it is DirectX 11, but if it is not supported by the system, then it is DirectX 9. You can also switch DirectX version by the NCGS_TOGGLE_DIRECTX command.

In the Linetype dialogue and in the drop-down list, linetype names can now be sorted in alphabetical order.

nanoCAD now continues to work for another hour following the loss of your license. This allows you to complete your work. You will be reminded periodically that your license has expired.
