Re: [CAD_CAM_EDM_DRO]A question of size managenent.

Sounds like a translator problem, or you may have a controller that doesn't support circlular interpolation. If your arc is truly a
portion of a circle, then yes, you should be able to replace all those G01 commands with G02/03.
If the arc is a spline then that is a different story. What translator/controller are you using?
