Import cross sections from CAD file(s)

Instead of placing cross sections by hand or using a boundary, it is also possible to import them directly from an AutoCad DXF drawing.
To use this method, please make sure you use a separate layer in AutoCad to store these lines.


Import dialog

To start importing the line data used to create sections, select the "Generate sections from DXF..." option by right clicking
the "Sections" folder in the project view. If the project view is not visible, you can show it by selecting "Project Explorer" from the "View" menu.

Select file

First, you have to click the "Browse..." button to select a CAD file. At this moment, only AutoCad DXF files are supported.
If your AutoCad file is saved in the DWG format, you can export it to DXF by using the DXFOUT command in AutoCad.

When a valid file has been selected, the layer names will be loaded and displayed in the dialog.

Select AutoCad layer to import
Select the AutoCad layer(s) that contain the cross sections


Select layer(s)

After the file has been loaded, you have to check the layer(s) containing the line data used to generated sections.
You can select one or more layers, please note that only LINE and POLYLINE entities can be converted to sections.

Options

It is possible to change the prefix of the section names, as well as a clipping area. When a clipping area (boundary) is selected,
all lines will be clipped within this area. When clipping area is set to "N/A" all lines will be loaded "AS IS".


Starting import

To start creating lines, just click "OK". After a few seconds you will see the imported lines in your project.
