Terrain from Audocad 3DFace elements

I have a surveyor supplied survey data in the form of an Autocad file. The terrain model is represented by 3DFace element. 

The surveyor can't generate genio or LandXML of the terrain.

What is the easiest (and accurate) method of creating a terrain model from the 3DFace elements?

  • Mark, I checked my records (it was back in 2005) but I don't have much detail. I didn't realize it was so many years back XM edition 8.9.2 or earlier. It's been a long time since I have had to import terrain models from CAD triangles I guess. 

    From memory the issue back then was slither triangles being formed between vertices (ie not along the edges of the original triangles)

    Things have probably changed in MX since then. I''l try it fresh in the morning.
    Thanks for your comments.
