How does viscosity really work?

Ok, so you have a small (steel) sphere placed into a graduated cylinder filled w/ 100% pure of a liquid: water, and another w/ glycerol. What is happening on the molecular level that makes the glycerol "more viscous" than water? Is it the nature of the intermolecular forces? IF so, explain.

Design Houses, where do I go from here?

I've designed about 20+ houses since '94 (pure talent....no schooling). I was told by contractors, that I don't need to spend 5 yrs. in college to get Mechanical Engineering training, because it'll be a waste of time. So....some of my drawings are as big as 18"x24", and in order to copyright the floor plans is to shrink them, but that'll be VERY expensive.

How do I transfer my plans to some kind of CAD program without redrawing? I've just got so many questions about who to talk to, where to go, and what to do next.......I don't want to be taken advantage of before I get my stuff copyright protected.
