G2 is a clockwise arc
G3 is a counterclockwise arc
this is always a direction not a positive or negative value of the x or z
if you start at the beginning of the arc and follow it to the end of the arc it will be clockwise (G2) on the front side
on the cut off side if you do the same thing you will find that it is traveling in the same direction (clockwise)G2
