The transparent model (red) is a copy of the same gray color cabinet in IsoDraw7.1, we can remove the ProE 3D transparency in 7.1 but how do we make an object (gray) transparent? ProE to PVZ does not import to 7.1 with parts that contains transparent properties, but *.ASM will import transparent part in 7.1.
IsoDraw 7.3 does not import transparent object, the part will import color, ASM or PVZ
BTW, PTC support forward most of our concerns to a developer department (black hole). We can also crash 7.3 and Creo Para 2.0 on demand.
