so i put a lot of work customizing the extruded counter top product. now I'm having trouble figuring out how to change the machine point to the bottom, and saving it back to the library. when i change the machine point from 4 to 3 in the "subassembly" and save it back to the library it always reverts back to 4. i need this changed so we can always cut the tops bottom side up, that way we don't have to deal with flip programs
