How can I make an assembly file independent from the part files that went into it? I tried converting it to STL then opening the STL document, but that causes problems with what I'm trying to accomplish.
Why don't you outline in detail what you are trying to accomplish and then we might be able to better pin point what you should do.
So, just use shrinkwrap? Any specifics? I don't want to lose my work AGAIN, so if you can please explain that a little since I don't want to take a risk.
