Well, maybe. I suppose it depends on your CAM program. I have Bobcad,
which I admit is NOT top of the line. For most tasks, it produces the exact
part I want, but may not use the most efficient approach.

I wrote some programs in C that each do one specific task more efficiently.
So, maybe I'm actually agreeing with you. Anyway, these programs are
not graphical, but fill-in-the-blanks. These do things like mill a
round pocket,
mill a rectangular pocket, cut a round or rectangular hole in sheet
material,
thread mill, drill a bolt circle, etc. I just find these things are WAY
faster to
use than creating a drawing and then generating G-code from that. If I
have something that gets to the level of lines tangent to circles, then I
WANT to have a drawing, though.

//// Thats one of the best features about Bobcad 18 and I'm sure others are capable of it as well is the ability to snap lines to arcs. I used to have to use a calculator and try to blend lines to arcs. What a PIA. I usually draw the whole part in the CAD section whether its mine or a customers. It doesnt take long and then I just use the "offset feature and generate toolpaths then go into attributes if its a complex drawing and make all paths different colors then I can "blank" the colors off the screen and just post code from the appropriate line/paths that I want. Bobcad receives alot of flack but for the money I think its a great program. One has to get the training CD's for it though. Without them is like learning the guitar without a chord chart. A customer was at my shop today and I typed his name in Bobcad, vectorized, posted the code and had it in Mach 2 and machining in little over a minute. Not cutting but doing the motion. He was impressed.

P.S. The machine is running fine Jon..no problems at all. That was a weird one with the noises and the drive.
