What possible purpose does the copy machine RMB option have? I have a part that needs two mill setups, so I made a fixture that'll do both. I thought I could set up the parts in the fixture, use the copy machine feature or insert a 2nd setup, so I could contain both programs for each setup on one file but now it doesn't seem that will work. also, once you "copy machine" is there any stinking way to delete it and go back to one machine? It is driving me crazy.. thanks..
