I need to design a building. Eventually, I expect that I will produce my drawing the way I build it, meaning with two-bys and sheet goods, but since I've never done this, I'm open to suggestions. For my initial conceptual drawings, though, I think I'll use solid geometric forms. So, for example, to produce a shed, I need a rectangular solid, a prism, and a couple of sheets for the roof. I expect that there are a lot of ways to do this.
One building is a "Tank House", which is a square frustum, with a shed perched on top. The base of the frustum is 18'x18' and the plateau is 16'x16', at an altitude of, say 16'. I think I could easily produce this shape as a wire frame, but that seems primitive to me and probably not the way someone with experience would go about it. Is it possible to produce a rectangular solid and then re-shape one end to make the frustum?
Thanks for the help,
