I have not flushed out the folder that I am working in and want to roll it back a few days. I tried using the older mfg version buy putting a .old after the newer mfg files. I did the same thing to the tool path and neither one changed to the older version. Which file do I need to roll back ? This thread is inactive and closed by the PTC Community Management Team.
