Thanks. Nicely you've choosen a different name, so I could add it on  
top of the same feature branch. Using this branch, there's now an  
"openscad" and an "scad" exporter. This should allow simple comparison.

Do you have a few already? Please add them to the repo. An SMD and a  
through hole resistor should show on most designs how things are  
expected to work.

One thing I've seen: You union full 3D geometry for copper and even  
silk. Wouldn't it perform better to union 2D first, then to extrude  
that? For silk and solder mask, 2D might be entirely sufficient.

Anyways, thanks a ton for the work. No documentation, no sample  
models, but I could actually see silk and traces of a simple design.  
Excellent!


Markus
