Yes I see after looking a little closer it is hardy going to break everyone's
programs.
only if you are using a lathe and
only is you are using a backtool and want it displayed as a back tool and
only if while displayed as a back tool you assume the orientation follows Fanuc
rules.
I bet the number of people doing that are pretty low, but will increase.
especially
if we fix AXIS to display a back tool properly.
