New in Topoplan

Version 22

The ability to split a drawing into prepared sheets for subsequent printing has been implemented. The Creating Frames command allows you to place view frames of future sheets on the drawing. The Creating Layouts by Frames command creates layouts based on frames with the desired design and scale.

image059.pngCreating Frames (CREATEVIEWFRAME). The command allows you to create frames in the model space for the subsequent formation of designed sheets. Each frame is a viewport of such a sheet.


Each frame carries information about the template, format and scale of the sheet. The design of the future sheet will be taken from the template in accordance with the format.


After the Creating Frames command starts, you can configure the options of future sheet for the frame:


Template – a template file containing a list of available formats with frame design. You can specify a template for formats according to standards or for a topographic tablet.


After selecting a template, specify the sheet size for the inserted frame.

Layout – Allows you to assign a layout format without reassigning the template.

Scale – selection of the topographic scale. By default, the scale of the created sheet is set according to the current TOPOSCALE:


After setting all the parameters, specify the position of the view frame in the drawing. In this case, you can use the nanoCAD precise positioning tools to snap to axial, auxiliary lines, mesh, points, or existing view frames. You can rotate frames and use other standard mechanisms for placing objects in the drawing workspace.

image065.png Creating Layouts by Frames (CREATEVIEWFRAMELAYOUT). The command creates layouts for designing a drawing according to previously created frames. Each frame has its own sheet, with the same design, format and scale that were specified when creating the frame.


The sheet’s frame and stamps are a dynamic block with parameters and attributes that can be edited in the Properties bar or using grips.

It is possible to design in form of GOST and topographic tablets.


For tablets, the Survey plot scheme, or the Sheets combining scheme are created.


image070.png Hide Frames (HIDEVIEWFRAMES). Frame hiding mode. Turns off the display of all created frames in the model space. Repeated execution of the command returns the display of frames.

image071.png Delete Frames (DELETEVIEWFRAMES). Deletes all frames created by the Creating Layouts by Frames command (CREATEVIEWFRAME).

image072.png Mesh Seal Holes (NG_MESH_SEAL_HOLES). If during creating a TIN surface or during its editing, surface discontinuities have formed, the command allows you to fill them with missing faces.



image075.png Add Mesh Edge (NG_MESH_EDGE_ADD). The command allows you to add edges to an existing surface at its boundary. An edge can only be added on a non-convex boundary (inner or outer) so that a new triangular face can be created without disturbing the 2.5D mesh.


image077.png Create Slope (NG_CREATE_SLOPE). The command makes it possible to create various types of conventional signs for slopes, cliffs, retaining walls:
  • Unfortified slope;
  • Fortified slope;
  • Steep coast with a beach;
  • Steep coast without a beach;
  • Stone retaining walls;
  • Wooden retaining walls;
  • Ground steep.

Before starting, the command checks the set topographic scale and offers to switch to the 2D-wireframe visual style.


After running the command, set the slope type and characteristics in the Properties bar. The options vary depending on the type of slope and how its edge is specified.


Next, indicate the location of the slope in the drawing. Slope edges can be drawn manually or created from existing drawing lines, depending on the value of the Specify slope edges option. The top and bottom of slope can be closed lines.



You can create a slope from one top point (hill). To do this, instead of specifying points for the slope top, select the Peak option from the context menu or command line.




In the drawing, the slope is selected as a single set of objects, parts of which can be moved.


image086.png Move point (NG_MESH_VERTEX_MOVE_XY is renamed to NG_MESH_VERTEX_MOVE).
The command now has the ability to choose when moving a point whether snap to drawing objects or take the height of the mark from the surface;

image087.png Add point (NG_MESH_VERTEX_ADD)
The command can now take elevation either from a drawing object or from a surface.
When adding surface points, the position of contour lines is now updated, if any have been drawn.

image088.png Delete point (NG_MESH_VERTEX_DELETE).
Deleting surface points now updates the position of the contour lines if they were drawn.

image089.png Import elevation grid (NG_IMPORT_ELEVATIONGRID). The GRD (Surfer 7 Grid File Format) binary format has been added to the list of supported formats.


image091.png Add structure line (NG_MESH_STRUCTURAL_CREATE). The ability to build retaining walls has been added to the command.



image094.png Export to LandXML (NG_EXPORT_LANDXML).

It became possible to export geopoints to the LandXML format. When exporting, the belonging of points to a group is saved. Export of geopoints and surfaces is disabled and enabled in the command parameters in the Properties bar.

image095.png Import Geopoints (NG_IMPORT_POINTS). The command for importing geodetic measurements from external text files has been significantly improved.


Now you can open multiple files for import at the same time.

New formats became available for import: CSV, SDR (Sokkia).

You can choose the type of imported objects: blocks \ geopoints \ primitives.

When importing survey files, it is possible to create blocks with the signature of number, mark, code (if available). The scale of blocks depends on the value of the current topographic scale.

If an existing block is selected when creating a point, then a new block with attributes is created, where the point sign is the block that the user has selected. If a new non-existent block is selected, then after the dialog settings, the block editor opens to edit the point sign (circle by default).

You can set layers for each element.

The result table has received additional features:

  • Changing the order of points, changing the order of columns. In case of incorrect initial data typing, you can drag one column to another by the header, mutually changing data in these columns;


  • If the corresponding box is checked, it is possible to create a polyline using filtered points;

  • Data filtering by any column is available;


  • It is possible to edit point data (name, coordinates, code);


  • If the import is to geopoints, it is possible to create a new group.

  • Multiple editing of cells is available using the SHIFT and CTRL keys. All selected cells are edited simultaneously. For example, you can clear a column if the data is not needed.

Saving of user settings (separators, colors, layers, fonts, etc.) to a file has been implemented.

Now the commands for surface editing and working with relief can be launched sequentially, without the need to complete the previous one.
The drawing explorer now displays groups of coordinate geometry points (geopoints), as well as sets of point marker styles and point label styles.



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.

It became possible to bind to geopoints in the Node mode.


Now a geopoint can be moved with transformation commands: MOVE, ROTATE, ALIGN, etc.

Commands to work with the measurement archive have appeared.


The work with measurements can be divided into 2 stages: collection of a measurement files archive and formation of a project underlays collection from this archive.
An archive of measurement files contains raw or preprocessed data, while a set of prepared underlays should be groups of geopoints ready for use in projects.

Filling the archive of measurement files
Measurement files are stored in the Geofiles folder. The path to the folder is defined in the Standard directories section of the Options dialog.
To add a file to the archive, the image104.png Add measurements command is used, with the help of which the required file on the disk is specified, if necessary, a new name is given to it, after which it is copied to the measurement archive.
If you need not only to save a raw file, but to carry out a full import at this stage, so as not to return to setting parameters later, then you should use the image105.png Save to measurement archive command. You need to configure the parameters in it, after which the result in the form of a DWG file is placed in the archive.
The measurement archive is displayed in the file explorer in Geofiles folder. By expanding it, you can view all archive measurement files.

Creating selections and forming a set of underlays
To work with points, it is necessary to form selections from the measurement archive.
Selections are formed by special commands in the form of separate DWG files, which are subsequently placed as external references in working drawings. Thus, the same selection (underlay) can be inserted into several different working DWG files.

To form a selection:
  1. Create a new underlay with the image106.png Attach geounderlay command.
  2. Import the required measurements into it from the archive using the image107.png Import measurements command.
  3. Configure groups of points, forming them, if necessary, and setting their parameters (styles). Enable/disable the visibility of the desired groups.
  4. Save the drawing to the collection of underlays as a separate named entity using the image108.png Save as geounderlay command.

The underlay collection is a separate Geofiles folder. The path to the folder is defined in the Standard directories section of the Options dialog.
It is also visible in the File Explorer as the Geofiles folder. By expanding it, you can view all the underlay files.
A new Conventional signs functional bar appeared. It is used to insert conventional signs into a drawing (for drawing topoplans of scales 1:500, 1:1000, 1:2000, 1:5000).
Before drawing conventional signs, select one of the topographic scales: 1:500, 1:1000, 1:2000 or 1:5000, in accordance with the required scale of the finished drawing.


The bar elements are structured by thematic sections and in alphabetical order.


The capabilities of the Conventional signs bar are not limited to inserting signs from an existing classifier. It is also possible to create your own signs or connect third-party libraries. To do this, use the buttons at the top of the bar.

image112.png Create element. Creating a new element of the library.

image114.png Create section. Creating a folder for thematic ordering of library items.

image116.png Create library. Prompts for a name in the command line and creates a new empty library with two ordering options: thematic and alphabetical.

image118.png Attach/detach library. Opens a dialog box that allows you to enable/disable the display of existing libraries in the Conventional signs bar. The source library cannot be disabled.

It is also possible to create new thematic sections, edit the composition of elements included in them, as well as delete any sign or section from the library.
