Main Options Tab

Main Options tab

The tab is intended to set the nanoCAD main parameters.

Common settings

Current profile

Layer profiles are designed to organize the work of various departments of the enterprise on one drawing file. At the same time, each user works with his own group of layers, controlling their visibility by means of nanoCAD.

Since the drawing design depends on the settings for the placement of design elements by layers and the current profile of the drawing, then for each type of object you need to set the option of placement on the corresponding layer in the settings (for example, for leaders, the Leaders layer is set).

Depending on the current profile, a prefix will be added to the layer name.

Thus, you can group layers created by users with the same profiles (for example, layers of objects built by designers - by the “KB” prefix, and by technologists - by the “T” prefix).

Perform the Refresh command when opening a document

The Refresh command is performed at each opening of a document (see Refresh command).

Line types

Standard nanoCAD objects are displayed with line types provided by GOST 2.302. Line thickness and color parameters are included in the general settings section of the Linetypes group.

Automatically disable the “Use paper space units for scaling” option

Automatically changes the nanoCAD setting “Use paper space units for scaling” for linetypes.

Change current linetype scale

Enables or disables the scaling of linetypes in standard objects when their scale is changed. When the setting is enabled, inserted design elements and database objects are automatically scaled in accordance with the scale of the Scale toolbar.

Use table of colors and weights

Enables or disables the use of color and weights table. If the setting is enabled, you can use standard colors from the table. The Compatibility mode value is used when working with documents created in earlier versions of nanoCAD.

Standard text weight

Standardizes the amount of text weight for all texts in a document.

Line color and width

This group of settings assigns the design option for certain types of lines.


Decimal delimiter correction

Controls the way to automatically replace the decimal delimiter character:

·         Do not correct decimal delimiter.

·         Use dot “.” As decimal delimiter – an option for programs that accept only a dot.

·         Use system locate decimal delimiter – decimal delimiter from OS localization settings is used.

Create and activate standard text and dimension styles in new documents and when changing standards

Controls the creation of standard styles. The default is Yes. Setting this parameter to No allows you to create new documents without predefined standard styles.

Explode Block References under drawing design elements

·         Yes – to overlap nanoCAD by objects, nanoCAD blocks are split.

·         No – to overlap nanoCAD by objects, nanoCAD blocks are masked (wipeout).

Enable enhanced grips

When this function is enabled, additional nanCAD grips are displayed on the objects, for example: “Flip”, “Insert leader line”, etc.

Set associativity during insertion of objects

The setting is enabled by default. When it is disabled, the snap of inserted objects to primitives is not active.

Use localized abbreviations of command keywords

Allows or denies the use of abbreviations for the command keywords described in the file with the .pgp extension and located in the nanoCAD installation folder.

Highlight color

The highlight color for primitives when it is required to specify them. For example, line highlighting when specifying for dimensioning.

Automatically switch keyboard layout to local language

When you call dialogues with fields in nanoCAD, the Russian layout is automatically turned on.

Show rectangle around objects

Controls the display of the bounding box around objects and nanoCAD blocks. When this option is enabled, scaling is disabled by Shift+RMB.

Automatically turn on snaps: Nearest, Endpoint, Quadrant, Center, Intersection

Temporary turns on the listed snaps when some nanoCAD command work.

·         If the option is disabled, some dimensioning modes will not work.

·         If the option is disabled, the Direction toolbar will not work correctly.

·         If the option is disabled, placement along the leader line, slope symbols, symbols of base and, possibly, other objects will not work.

To show the toolbar “Direction” automatically

Controls display of the Direction toolbar, which appears when inserting database objects and in a number of other commands.

Scale dimensions

Controls scaling of nanoCAD dimensions with help of the Scale toolbar.

Scale texts

Controls scaling of nanoCAD texts with help of the Scale toolbar.

Scale hatches

Controls scaling of nanoCAD hatches with help of the Scale toolbar.

Ignored layers

Specifies nanoCAD layers for which primitives located on them will not be overlapped by nanoCAD objects.

Unplotted layer

Specifies the layer on which nanoCAD objects excluded from plot (group markers, non-printable markers, mark anchors, shown dependencies) are placed.

Mini-toolbar for viewports

Controls the display of special nanoCAD mini-toolbar , by the right click inside the viewport in a layout.

If the option is disabled, then the right click inside a viewport will call the standard nanoCAD context menu.

By double-click

Establishes the rule according to which double-clicking on an nanoCAD object will call the edit dialog for this object or the properties bar. The setting has four parameters:

Program objects – when the option is enabled, edit command will be opened by double click, when disabled – object properties window. Applies to objects of all types, except for dimensions, texts and multiline texts;

Dimensions, Texts, Multiline texts – the option is simila to a previous one, but with help of three checkboxes it controls the result of double click on dimension, text and multiline text.


ESCD Standard:

SPDS Standard:

Use symbol scale

The option is disabled:

·         Design elements are inserted as 1:1 scale.

·         Database objects are inserted with the current scale (line type scale is equal to 1).

·         Measurements of dimensions (if they are not inside formats and not associated with nanoCAD Organization objects) take a scale factor that is reverse to the current scale.

·         The mode is signaled by a small letter m on the Scale toolbar.

The option is enabled:

·         Design elements are inserted with a current scale.

·         Database objects are inserted with the scale specified in the insertion dialogue box (by default 1:1). Line type scale is taken from the current scale.

·         Measurements of dimensions (if they are not inside formats and not associated with nanoCAD Organization objects) use the scale factor 1.

·         The mode is signaled by a capital letter M on the Scale toolbar.

By default, for the Organization standard the option is enabled, for ESKD format it is disabled.

Text wipeout offset

Sets the default offset of the geometry mark from the text.

Cut CAD-platform elements

Controls the overlap of nanoCAD primitives by design elements. Is reverse-acting. Acceptable values: No, Cut, Wipeout.

Wipeout – closes a primitive.

Cut – cuts a primitive section. When deleting or moving, the cut primitive returns its state.

No – does not overlap a primitive.


Enable hints

Enables or disables the display of hints in the notifier. The option does not apply to a notification with the Error status.

Avoid mouse pointer

Enables or disables the mode of automatic displacement of hints not to interfere with the selection of objects.

Hot keys

Hot keys are assigned to open Quick Options and Notifications (notifier) dialogue boxes.

Databases access

The database includes, in addition to standard elements, table and format templates, bolted assembly templates, groups and markers, as well as examples and other custom elements. The choice of a specific database is determined by configuration of the path to the data source.

Data Source – a path to the file of the standard objects database.

attention! When placing the nanoCAD database in a network resource, it is necessary to allow all users to write to the folder where the base is located. In this case, the file with the database itself can be read-only (then users will not be able to change the contents of the network database).

nanoCAD provides for work with both databases of standard MS Access products and MS SQL. When you click the  button, a dialog for specifying a data source appears in the Data Source field.

When using the MS SQL database, it is necessary to specify the server name in the Server field (along with the name of the SQL database server). For example: SERVER or SERVER\SQLEXPRESS.

In the Database field, it is necessary to specify the name of database to which connection is made.

If the MS Access database is used, it is necessary to select the Database source - PostgreSQL switch, and then specify a path to *.mdf, *.mcs files of the database. (A path can be a network one.)

Note: Database access settings are interface settings. Problems can occur when using disk compression

with connection to local databases (for 64-bit versions).
