I'd like to design some things with bolts, fan belts, levers, motors, etc. So I'd add a bolt here, drill a hole there and maybe take it apart and rearrange. I'd like to do it in 3D and found SketchUp.
Can it be used to design, create and print out dimensioned components for manufacture and assembly? I'm not knocking it, but is Sketchup anything other than a really good conceptual visualization tool?
