About model and data exchange with 3rd party solutions: Revit, Solibri, dRofus, Bluebeam, structural analysis solutions, and IFC, BCF and DXF/DWG-based exchange, etc.
After successfully importing (File Special>Merge)a sketchup 3D file into AC 17, The resulting Morph is a quite lively bunch of polygons that are quite disruptive in obtaining a useful model to manipulate. I read online of a manner to eliminate extraneous polygons from the import on a windows machine, but not macintosh. Any suggestions?
