Thanks for that additional info, rabbit. Very encouraging. Knowing my AutoCAD experience will carry over somewhat is nice to hear.
I put together a little presentation, a render, some 2D drawings as I would've produced in AutoCAD, and exported a 3D PDF page where you can see the model and spin it around right there in the PDF and sent that off to my boss. I'll see what he thinks and if he's into it, I'll definitely be looking more into Rhino.
