I agree. (but I can list many other things for which this is true: relative/absolute mode, coordinate system offsets, inch/mm modes, tool lengths, IJK/R arcs, diameter compensation, ... Convenience of programming alone can be an adequate reason to have a feature.) > For certain types of application, polar coordinates are much easier to > use than Cartesian. I agree. > Polar coordinates would be used if they are available. I agree. I can't tell if you're saying you think the change should be incorporated or not. Can you clarify please?
