Make Any Shape Board in Eagle

circuit2

[Bryan] has been working on a very nice analog LED clock circuit, but when it came time to lay out the parts in Eagle, he was somewhat miffed by the inability to create designs in his Eagle boards. Eagle is a fine tool for laying out circuits, but when it comes to making strangely shaped PCBs, Eagle just isn’t the right tool.

The solution to this problem was to create the board outline in OpenSCAD. The desired shape of [Bryan]’s clock was easily designed, but importing the shape into an Eagle layer was another matter entirely.

OpenSCAD, though, can output 2D shapes to the DXF format. Getting the DXF board into Eagle required [Bryan] to write a script that outputs Eagle WIRE commands. Pasting these commands into the command line gave [Bryan] a perfectly shaped PCB.

Since DXF is supported by every drawing package on the planet, [Bryan]’s 20 line script could also be used for much more intricate designs. If you have an incredibly complex Illustrator drawing that deserves to be a PCB, it doesn’t get much easier than tossing it through a script.
