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.

 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.

 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.

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

• Unfortified slope;
• Fortified slope;
• Steep coast with a beach;
• Steep coast without a beach;
• Stone retaining walls;
• Wooden retaining walls;
• Ground steep.

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.

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

 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.

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.

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.

1. Create a new underlay with the Attach geounderlay command.
2. Import the required measurements into it from the archive using the  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  Save as geounderlay command.

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.

 Create element. Creating a new element of the library.

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

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

 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.
