dxf2pcb
Convert DXF drawings of circuit boards to gEDA-PCB files.
...It is designed for two purposes: One is to generate a PCB snippet from a mechanical drawing (such as a board outline), the other is to produce element files from CAD drawings. PCB snippets are easily imported into an existing gEDA-PCB project using File -> Load Layout to Buffer. Generated element files are ready to use (except for special cases like no-paste flags and rounded pads).
