On the last 2 projects that I have had to import .STP files, some issues have arisen. small surfaces in the corners of objects are missing and also excess construction parts are imported. When I imported the same STP file into another CAD program for the mac there were no missing faces, the construction parts were not there, and the parts were grouped better. I could send Rhino a file but could not share it with everyone.
