I have been testing a cutting design program called MAKE THE CUT is is a vector cutting program used in the crafting, vinyl ,paper cutting world.
My wife and daughter use it for crafting with a CriCut. I was watching them work and noticed they were doing the same things I did for plasma only they did it 10 times faster than I could and in some cases did a much better job of it.
SO after a little studying and testing it is a VERY nice program that CAN be used in plasma design work. It outputs in several of the native Vector modes and it is possible that they could write a plugin to output it in DXF format as well.
I take it from SVG straight into Scam.
Might be worth a minute to check it out, the price is VERY reasonable. and the support seems top notch.
Just a thought, (;-) TP
