Gerry-
What's in my mind are the intricate relief pieces you see (I guess they'd be 3D). There are complicated designs complete with circles, arcs, and freehand draws. Then the CNC comes along and with a single pass, never crossing the same point twice, manages to lift and dip with perfect accuracy. I'm sure it can all be worked out mathematically, I just don't know what the heck that math is! If this doesn't make any sense, don't worry, my brain is often on the wrong plane
