Hi,

My approach is:


Create 3D-models with the same "descriptive name" as the footprint has 
(only a different extension, avoid spaces here), see my library of 
3D-models on Github.

The (pcb) exporter generates an OpenSCAD file in which a pcb with 
maximum X-, and Y-dimensions (and a nominal thickness 1.6 mm) is 
defined, and where 3D-models of named parts are included (like in a C 
program) and inserted on X-, Y-coordinates and on top/bottom side with 
proper orientation.

So basically no 3D-modeling stuff has to be built into pcb itself 
because OpenSCAD is to do all the rendering and visualisation.

Same line of thought can be applied to any other 3D exporter :)

Kind regards,

Bert Timmerman.
