That suits me just fine.. OpenGL _likes_ rendering triangles, and any other geometry primitives are extra work to implement ;) > A decent pcb would make for > a pretty large stl file if all the vias and pin holes were to be > modeled realistically.

I've been looking for a format to _import_ 3D models of components for a quick "rough" viewing within PCB. I concur that we probably don't want many of the suggested formats for CAD interchange. I concur with your other points, but think I'll play with VRML models for now. I'm _hoping_ that there will be a route to do: Serious component model in CAD -> VRML for use within PCB. -- Peter Clifton Electrical Engineering Division, Engineering Department, University of Cambridge, 9, JJ Thomson Avenue, Cambridge CB3 0FA Tel: +44 (0)7729 980173 - (No signal in the lab!)
