I am building a structural assembly using the structural part configurator in the Toolbox. I have been using "Save as Copy" to break the link when saving the created parts. I am making significant changes to the parts that have the new name. When I place them in the assembly, then work with the new parts there in the assembly, they appear correct. When I save and exit, then reopen the assembly, all the parts have reverted back to their original toolbox construction.
Must be a switch that I do not have flipped. Any Help?
