    what exactly is the benefit of 3d sketching?

    If you're in machine design and you're just dealing with simple shapes you can machine on a lathe or a Bridgeport, you probably won't find a use for them. But if you're dealing with any sort of wires or hoses, molded parts with complex geometry, etc., they are invaluable. And, of course...

    SolidWorks 2010 Electrical Routing

    Enginerd, There's a "Routing Component Wizard" under Routing->Routing Tools. I don't think it's documented in the tutorials. That should help you get started.

    Sealed Rectangular Tubing - Stress from temp. increase

    Hello, We're designing a structural system that will have HSS 8x4x5/16 members approximately 8ft. long spanning in between two S12x31.8 beams. The tubes are water-tight welded to the edge of the structural steel; we need these tubes to be water-tight because the structure will be partially...

    Driveshaft Critical Speed calculation

    Hi all, I'm looking for a way to roughly estimate the critical speed for an automotive driveshaft. It's a typical RWD driveshaft -- a hollow tube supported at each end by a U-Joint. 3" O.D., .083" thickness, 4130 steel. We have lengths from 10" through 60" in increments of 5".
