Good morning, excuse me if I reopen this discussion,
I have a similar problem, that is, I would like to import into sketchup (8) in rhino (4) and I can easily, only thing I see not the clean beautiful faces, but I see diagonal lines, that is, everything is divided into triangles... I tried to export 3ds and dwg but I always have the same problem. Does anyone know how to help me? Thank you.
