There used to be an option to delete the cam setup (all the manufacturing data) from a part (.prt) file under Menu; Tools; Operation Navigator; Delete Setup. This is not in the software anymore.
SolutionThat menu option was in place through NX2206. As of NX2212, the menus have been restructured and this same function is now found under:
Menu; Tools; Resource Bar Tabs; Operation Navigator; Delete Setup
