Lines From CAD

This function is used when you have CAD lines on top of your DTM model, and you want the DTM lines and points included in the model to coincide with the CAD lines. The CAD lines could be from a drawing attached to the project or simply drafting completed during that session.

Terrain Mode Model Menu › Lines from CAD


Convert CAD lines on all layers Check to have the processing of CAD lines to take place on all CAD layers.
Convert CAD lines on visible layers Check to have the processing of CAD lines to take place on just a visible CAD layer. Follow up by selecting from the dropdown list which CAD layer you want.
Interpolate from Choose the DTM surface from which new points will have their elevations interpolated.
Store on surface Choose the DTM surface onto which new points will be stored.
Point name Type in a name that will be given to new points.
Create DTM lines as breaklines Select this option to have breaklines drawn between points coinciding with CAD lines.
Create DTM lines as feature lines Select this option to have feature lines drawn between points coinciding with CAD lines.


We will use the CAD to Lines function to convert the Red CAD line to DTM points joined with breaklines.


Once the function is complete you can see the breaklines below the CAD lines. Switching off the drawing, and displaying the new surface (surface 2) you can see the new interpolated points and breaklines.
