Break Arcs Into Lines Issue

Hi Scott,

#1 :

the following code works fine with G3 but breaking the arc into lines the center of the helix is shifted in -Y direction with every 360 degrees.

Seemes to be a calculation problem.

Could you please add a default value in the Break Arcs Into Lines dialogue ' Enter maximum path deviation distance:' ?

Thanks
