I have been using IronCAD since TriSpectives 1.0. My current Version is IronCAD 8.0. Since I don't have the latest version I can not open the .ics files made with newer versions here at GrabCAD. I can import many different 3D formats, can anyone offer a solution?
AS Cliff says, request a STEP, ACIS, or PARASOLID file. I prefer STEP.
