Sketching acme threads

Don Aldridge May 28, 2008 1:21 PM

I am trying to do a revolve sketch that includes acme threads. I need to detail out the actual thread for the production drawing so I don't want to use a cosmetic thread. Lets just say you are drawing a ball screw type shaft, what is the best approach? There are also several other details on this part that make the revolved sketch what I thought to be the simpilist approach (in my limited experience!)
Thanks, Don Aldridge

The easiest way I know to do "real" threads is with a helix driving a sweep. Is this not what you envisioned?

  You don't actually need the helix. You can sketch the cut profile and use the Twist Along Path option.

    Where do I find the twist along path option? I assume I would do the sketch profile as a revolve, correct ?

      You need to sketch an axial line first then do a sweep of your profile. Twist along path is in the options, and you can set it to # of turns.
