I never have setup a threading tool in Mastercam the way Roger has set it up Sorry Roger. I always program Zero to the edge of the tool. I want my tool to go to .999 up against a 1.000 should then I can program .999 and know if the operator touches of the tool correctly it will never crash. By going off the center of the tool you run the risk of a crash. I do it like Peter is suggesting and never had a problem making a good thread yet.

I see. Well if/when you do start putting manufacturing stuff in there it would be cool to trade ideas and see what's working well for you. Feel free to PM me.

Hello Bill, Not sure if you like this but this is what I've got for detailed tools list...
