Hi, folks. Could someone guide me to some comprehensive Sketchup tutorials/guides, mainly for construction of residential structures, houses, sheds and the like. I know there's a lot of stuff out there, which makes it difficult to know where to start. Plus it seems there's a lot of "Sketchy" guides too. So I'm looking for something that starts with the basics and works it's way into the more complex concepts and tools. It could be in video or book form, preferably free, but I'd be willing to pay for something if I think it's really worth it. Thanks.
