I had mastercam crash on me causing it to automatically reboot to my last save and when it did my solids got messed up. Basically everytime I try to regenerate any solids it gives me an error saying "Error reapplying operation. Restoring model state" And I also get an error when trying to regenerate my toolpaths that says "Parasolid(R) Kernal Interface Error: PK Error Code 22- tag is invalid or dead" Is there anything I can do to repair my solids or am I gonna have to make up hours of work?
