The main point I was trying to make is the file is saved into Acrobat PDF as a Solid &
file size is very small.

No intention to have a peeing match over who's viewer is better, cheaper or free-er.;)
I use PDF's with my clients and they have no intention/desire to install or learn a 3D program.

I also posted this because I'm finding that the files load into 3D Reviewer the same way
as Acrobat, as separate components (non-grouped faces) and was hoping that MoI ver.2 style
groupings can help to pre-group components for coloring/material before saving/export.
