Does anyone have CAD that they can use and use accurate dimensions? I'm looking for a design for a small work bench. Something I can put my trucks on to work on them. My idea is a bench with the dimensions of 4'-0" long, 2'-6" deep, by 3'-6"-4'-0" high to the table top. Im thinking about a 1" tall lip around the outside top of the table top to prevent things from rolling off. And a 6" high "backstop". I'd also like to throw 2 or 3 drawers in as well. not too big of drawers. But i was thinking 4"x4"'s for legs?
