Hans;

I'm just started with CNC machining. The little bit of GCode I've run,
I've written by hand.

I'm now investigating software to make this all easier. BOBCad is
pretty cool ( a friend showed me some neat tricks ), but just a little
pricey for a guy playing at home.

It was my plan to do as you do, use AutoCAD ( which I already own and
kinda know how to use ) and some DXF to GCode conversion program.
However, I do have a few questions.

1. How does "Ace" handle 3D , as in pockets and whatnot. Or are you
left to manually add Z commands after the fact ?

2. How do you deal with tool widths? CNCPro, which I'm using ( and
quite like, with a few exceptions ) doesn't handle G42/G43 commands, so
I'm really hoping you have some "magic".

My only idea is to draw the part on the "PART" layer, offsetting it to
the "outside" on the "TOOL" layer by half the tool width, fillet the
corners, then DXF the TOOL layer. Extra work, to be sure.

Thanks in advance.
