PCB output for a "3D-view" in Blender (or AutoCAD if you live in the
"other" universe) is somewhere on the bottom of my todo list.

To keep things decoupled from the pcb perspective I would suggest one
(or more) plugins/exporter-HIDs that generate a python script for use
with Blender.

For the users in the other universe I hope to conclude my pcb-dxf-HID in
the next months or so, although I'm not in a hurry so it could take
longer.  AFAIK QCAD doesn't do 3D DXF, so this option is still not
possible.

I do happen to have some AutoCAD 3D models of electronics parts at:

or

http://www.xs4all.nl/~ljh4timm/downloads/sat/

(in ACIS format (ASCII)).

Kind regards,

Bert Timmerman.
