I am playing

figure out how to drive Wings32 to create a new model!
I'd strongly prefer to do 3D models with a full fledged 3D CAD
application. Preferably with the CAD app I use for the rest of my
construction work. That's the benefit if pcb would communicate
the full information of the layout to a free 3D CAD app. This app
would shoulder the tedious import/export to the complex formats
of the real 3D CAD world -- IGES, STEP, DWG, ...
Did I mention, that mesh formats are a one way road, when it
comes to construction?

again ;-)
I knew that ;-) - no need to convice me. Still if pcb is to display 3D
models with OpenGL,
a tessellation of the scene is required. Personally, I'd prefer
something like the winged-edge
data structure of BRL-CAD (not it's UI) to handle intersections of
BREPs. Many years
ago I started to define something like that myself, but never got enough
motivation to
to complete it - still, I can help you (and my own demo ;-) with that.
You might have a look at http://gts.sourceforge.net/ .
