My goal is to generate ground-plane section lines from a terrain model.
I created the terrain model from contours with x, y, and z coordinates and then performed the “meshpatch” command followed by the “drape” command to create a surface. In order to cut section lines from this terrain, I drew rectangular surfaces perpendicular to the terrain in order to generate an intersecting line that is the section.
When performing the “intersect” command, the mesh/terrain is not able to be selected.
What is the best way to generate a section from a terrain surface? Why am I unable to select the terrain when "intersect"ing?
