SLC File format for 3D printer

Graham,
I reluctantly have to agree with you that the SLC format is the way to
go for 3D printing. I spent a lot of time exploring different hacks up
to and including Java3D, Sketchup (Ruby, too slow) and a couple of
other CAD programs with no luck. I did find one interesting one,
Boxford RapidPro, which does almost what we need, but not quite.

I've been putting off doing a Rhino upgrade as mine is version 2 and I
really only ever used it as a viewer/converter.

Can you point me to a layout of the SLC file? I haven't had much luck
finding it. There is a vtkSLC reader but I'm reluctant to learn yet
another technology. Java3D in a day was bad enough.

Thanks,
Roger

PS. I bought a bundle of 5 new Lexmark injets on Ebay for $49. I'm
going to have plenty of spares. I'm not going to start the hardware
until the software is done.
