If you save as v12 .dxf the splines will automatically be converted to polylines in the .dxf file. There are also some freely available spline to polyline lisp conversion utilities you can download.The problems I have with it is that it doesn't take splines (coming from Autocad)so have some extra work to redo certain things in polylines.

I just bought licenses for Mach3 and LazyCAM. I've been playing around with LazyCAM and can see where it has some power but its been a struggle to figure it out.
I can cut 2D out just fine but if you want to cut out a box for example where you have to cut a pocket out then profile the outside I'm having some issues still. Tutorials seam to be few and far between...
Anyway, just making my mark on the LazyCAM forum
