Gawd, what a tool! Thanks again parabellum.
If I end up with an empty page when I load the converted .dxf file into my CAD program, does that mean that there were no vectors used in the original .pdf and were just raster images to begin with? Some of the files I tried came out FANTASTIC but some came out as just a border and nothing else came through.
I also had some scaling issues but nothing I can't figure out.
