Hi all,

thanks to the support of Bdale and Altus Metrum, LLC, we have a new, 
working openscad exporter. The code is young and largely untested - please 
send me bugreports to get it fixed.

Sample board and renders with a small board of 2 resistors and 2 
transistors: http://igor2.repo.hu/tmp/openscad/

The exporter supports:

  - arbitrary shaped outline

  - top/bottom copper (optional)

  - top/bottom mask (optional)

  - top/bottom silk (optional)

  - holes (optional)

  - element models (optional)

As the sample shows, we have full support for compositing layers (the 
'inv' text is a positive silk rectangle and text on a negative silk 
layer).

A more complete feature list can be read at 
http://repo.hu/projects/pcb-rnd/user/07_io/export_openscad/preliminary.txt


Our policy at pcb-rnd is that pcb-rnd itself is not going to support 3d 
(3d rendering, 3d editing, etc.), but only "2.5d": 2d layers with a 
detailed layer stack model that will soon understand thickness and 
material. We also support 3d export and let openscad do the 3d related 
work. Openscad is very capable: if there's an enclosure model and we can 
export the PCB, openscad can be scripted to determine if the PCB fits in 
the enclosure (the intersection object between the two models is empty).


Regards,

Igor2
