This is something that really interests me as well. I'm nowhere near as electronically proficient as GTech13 seems to be, but I'm pretty strong on the overall creative design and mechanical stuff. I've been toying with the idea of designing a whitewood based on a custom theme and wondered where to get good CAD files of standard Williams components like flipper assemblies, pop-bumpers etc...

Anyone have these?

I don't currently have Solidworks, just basic AutoCAD, but pretty easy to draft up any 2D or 3D models with that as well. Not as forgiving as Solidworks though. For visualization, we just use 3DstudioMAX. A lot of the work I do is architectural in nature so these two pieces of software are more suited to that. Either way, I'd be happy to work on some CAD blocks.

If you watch TILT the pinball 2000 documentary, there's a great scene where George Gomez is drafting up a 2D plan of a PF and he just plops a bunch of these ready-made Williams parts in place. That would be sweet to find.
