Converting DXF to TP3

I think I got it working correctly. Kubla Cubed generates the surface as a Polyface Mesh in the CAD files. A Surface has to be created from this PolyFace Mesh: https://forums.autodesk.com/t5/civil-3d-...-p/6954680

I got this to work once. It was a surprise when I finally got it to work, so hopefully I can do it again


If someone here knows of another way to do this conversion outside of Civil 3D (AutoCad), that would be great. Or maybe Kubla Cubed can do it. The whole point of using Kubla Cubed was to avoid paying for Civil 3D, which now I have to use to make this one conversion for Topcon.
