It is my understanding that Pro E/PTC does not support the use of Striped wires in its RSD and Pro/Cabling modules. This is really bizzare being that this is so common in the electrical world.
After asking them what alternative technique they would recomend to achieve something similar their tech support sent me the following message: "After further investigation, it has been determined that the functionality you are looking for is not currently part of the application specification."
So I gues I'm wondering what are some of the workarounds that everyone else in the Pro E community have come up with???
