How do I add 3D viewing capabilities as I build my parts library? I have step files to add to each part but I am not sure how to add them and how to view them. This would be good to verify that I built the part correctly. Also, if I could view my PCB in a 3D environment, I could see critical features more easily by rotating the board, or see internal features. This would also be useful when I send the design to the Mechanical Engineer to import into Pro E for fit checks with other PCBs and Mechanical enclosures and features.
