Does anyone know if ProEngineer supports import of IDF files version 4.0? I currently have IDF files of my PCB's in version 3.0 but the tracks and pads are missing, and I was told they do not exist in IDF V3 but will be included in version 4.0. Another way would be to import VRML files, but I cant get that to work. It simply gives me an empty PRT. Any ideas?
