Learning Surfaces

I noticed that there are only two examples of Surface Geometry in the Solidworks help files. "Surfaces", and "3-D Sketching with planes". Is there somewhere I can go for the real basic principles? Maybe explaining the many individual features that make up the whole of Surfaces. The Community College that I attend doesn't offer Solidworks Level II, at all. Level II involves Surfaces, Photoworks, Animation, Cosmoworks, Routing, etc. I did see some real nice Powerpoint tutorials on the net from Di Monti web site, and also from a site by Lombard, but I believe they must be designed for someone that posesses basic knowledge, at the very least, and knowing nothing at all about surfaces, I was totally lost going through them. The people that made the tutorials were obviously brilliant people, but taught way beyond the level that I am at, at this point at least. I am hoping to find an instructor with the ability to explain the mechanics of Surface Geometry at a level that a complete novice will absorb. I am thinking that there must be some real basic info somewhere, like there is explaining the fundamentals of Solid Geometry. I do have two books by David Murray, but for some reason Surfaces is not covered at all. Can I be placing too much attention on the value of knowing Surface Geometry? Is there something that I am not knowing here? Why is there not the same amount of literature available for both phases of Solidworks I wonder? Or maybe I am simply deficient in my ability to locate it? Carl
