I'll have to try that.

Also Photoshop and Mac OS X Preview etc. support Collada, so perhaps that's where the world is converging instead.
Well, that's still using Acrobat Pro which is about $350. I was trying
to stay FOSS.
I did have some success using Meshlab. It exports a UD3 file with a
simple latex script and then you can use pdflatex to create the PDF.
It works but the default orientation of the model is strange and I get
a divide by 0 error if I try to change it.
I exported a COLLADA version but it does not export a latex file for
embedding in a PDF.
