Hi, I am a product designer working in Rhinoceros Version 5 SR11 64-bit. My colleague in China is working with Solidworks 2014. I have converted the Rhinoceros drawings into STEP (AP214 Automotive design) or IGES (default or solidworks surfaces or solidworks solids) or ACIS (solidworks) but I get always the same answer: he can open the drawings but not edit them. And the drawings he receives (STEP,IGES or ACIS) are “flat” in 2D but I only send him 3D parts and assemblies. Am I doing something wrong or should he open the drawings in a special way. What else can I recommend them to do.
