Michael, thanks! I have a demo version of Rhino with a few saves left, so I did as you said.

The STEP file imported into Rhino okay and I saved out a 3DM file. When I opened up the file in MoI there was nothing in it.

Also, I don’t know Rhino much at all, but I couldn’t find any material or color assignments anywhere. Should I assume that color information isn’t being preserved?
