Thanks for hooking me up with the demo. I was not able to get done what I needed to, though. I want to import dxf files of art that I made in Adobe Illustrator, then turn those shapes into polyfills on my gerber files. I think that Adobe makes weirdly formatted dxf files.
I was able to import one of my files, but unsuccessful in making the shapes filled or combining with another gerber.
If you are interested in using Adobe and outputting gerber with fill, than use ACE 3000 to convert PDF/Postscript to Gerber; using DXF from Adobe is the wrong way to go. Here's our website page explaining how to convert Adobe (Postscropt/PDF) to Gerber with Fill, etc.
