I'd go even farther... there really isn't much point in a 3D rendering
of a PCB by itself -- that is just eye candy for posting in your blog.
But... being able to import a model of an PCB into your mechanical
design as a part, now *that* has value. What I'm interested in is
getting the screw hols in the right place, making sure that the big
'lytic caps don't bonk into a rib or strut, and make sure that the heat
sinks actually *do* end up in the air flow.
