Importing files from Civil 3D

Is there a way to import an Civil 3D geometry into RHino 3D, then create some surfaces or solids and then export it back to Civil 3D?

Hi @mario_pende
Since Civil is an Autodesk product my best bet would be DXF or DWG; I’d be surprised if it doesn’t handle both formats and Rhino does as well. Have you already tried moving data back and forth - and what kind of problems did you run into, if any?
