At times I will have an assembly with multiple shares of a part (for example, 10 instances of the same screw). Later I find that the original part won't work and I have an entirely new part that I want to use in its place. What I would like to have is a command to replace one part, and all of its shares, with a new part. I know that I can use the Multiple Positioning option with the Create Share command, but I would like a command that was more intelligent. Obviously I would need to position and orient the replacement part to correspond with one of the existing shares, but the software should be able to take care of the rest.
