    Re: Twist

    In BobCad, you'll have to generate the upper and lower "spirals" and also the root spiral, then use a skin command...

    Manually building it. there wont be a "sweep profile" command to spit that out in 1 go...

    Re: Twist

    Sorry, my bad. That was for "Bolt threads".

    For a "Screw", much simpler.

    Make a helix of ypour screw. Put a single straight line down the middle of the helix center. "Cross section" the helix and the pole.
