HELP import surface from Autocad CIVIL 3D to ICEM CFD
 

Hi guys!

I am desperate, I need to import a contour surface, which I perform in Autocad Civil 3d, but I could not get the ICEM CFD to import it.

Eh was able to import the curves level of google earth, but the surface made in Civil 3D, that no!

If anyone knows how to do it, I would appreciate it all my life.
