Very nice.

Why do the hard render work, when there is blender available with a 
mature multitude of shaders and light options?

I'd take it as a nice-to-have.

I'd model "my" parts if I can use them in some kind of 3D mechanical
CAD. The incentive is the ability to make the circuit fit into some
kind of space -- such as a specific enclosing. I already made about
30 3D models of switches, trimmers and enclosings for this purpose. 
They are in varicad format. So a way to convert from varicad to 
whatever format pcb can read would be a plus. Most likely, this would
include STEP as an intermediate format.


> 3. What format would people like to make models in?

FreeCAD, or any other format, I can produce with an open sourced 
CAD application. An exception is BRLCAD. I would only dive into 
this particular suite if someone paid me real money.

Methinks, this is a dead end with regard to mechanical CAD. No 3D
construction suite I worked with, was able to import/export VRML 
in a decent way. They all converted the geometry into some kind
of mesh --> Loss of information, large files.
