code generation?

Hi again to all--
Been playing wiht a couple demo software packages while waiting for my
CNC mill to arrive...all I can say is ouch!...

Well, ok...I got my layout for the first piece saved as a AutoCAD .dwg
[and also as a .dxf]...it's milling a design into the face of the
workpiece, all one depth, basically 2-D work. The AutoCAD is all
linework, no more.

Tried the SuperCam demo...it splits the drawing into two parts and
blows one of the two parts up to about 8 times the size of the rest.
Tried the DeskCNC demo...it only allows me to select the two parts
that SuperCAM blows up.

Tried the AutoCode demo...it seems to do exactly what I want,
painlessly...but the demo version won't allow me to save anything and
the bought version is $2500!!!

Back to AutoCAD for Dummies...

I;m open to suggestions...actually, I'm kind of overloaded and don';t
know where to start asking questions...I'm self-taught to a fairly
'power-user' level on Word and Excel and the like...but I'm feeling
that's a real handicap here...

Thanks in advance.
