Re: [CAD_CAM_EDM_DRO] Comparison of Cadd

That's great....provided your working for a big shop that can afford the
expense required for doing SLA work.

When working for a small shop...or for yourself...the watchwords are "KEEP
COSTS DOWN"!

Also, since I'm "retired" and only make a few parts at one time using
manually operated machines, drawings are a necessity not an after thought.
In some cases I COULD make parts without a drawing....all I need to do is
get a clear picture in my mind and go from that. IN that case, I wouldn't
even need drafting tools let alone a computer and software.
