Virtual Parts Pros and Cons

One of our VAR team suggested looking at the use of virtualparts. I have tried using them on a welment. A draw backs is Idon't seem to be able to do a 'save as copy' for a part that is toremain internally in the assembly.

The advantages I found were that it reduces the number of partfiles and simplifies naming of parts.
