OK, I got use of a computer with XP and have been learning SU7. Pretty cool. As a kid, I worked just long enough as a carpenter to be dangerous, but not to read blueprints. Now I'm trying to create some. As a mechanical CAD designer, I'm used to working in thousandths of an inch. I'm sure that level of accuracy is not needed for architectural drawings. Or is it?
Main question. When I'm creating detailed drawings of the deck I'm repairing, do I create them using nominal dimensions (2"x4") or actual dimensions (1-1/2"x3-1/2") for lumber? Seems like it should be the later, specially for cutting to length. What kinda tolerances are typical for framing and the like?
