My apologies for not keeping up with updates on earlier posts on this topic.  A recent message made me aware that I had not provided my latest version of this button macro for Auto Tool Zero.

This new version adds prompting to input the tool diameter at the beginning, and auto-calculates the tool offset.


This code was last updated on 12/6/2011...time passes

Holler if you have any questions.
