Hi Michael,

Concering dxf I only work with 2d lines and not with solid objects.
I understand nccad actually works with polylines so that's the problem.
As Rhino is a quite expensive conversion tool. Can you suggest a more affordable one?

Hi nekro, you might try ViaCAD: http://www.punchcad.com/p-9-viacad-2d3d-v8.aspx ($99)
