Pipe ( NPT ) Threads again

You have customers requesting pipe or NPT threads be added to the thread tool... repeatedly.

OnShape can not be a credible product development tool without pipe threads.

    Pipe taps are available in the hole tool - won't that work for you?

    @william_lucke We added tapered pipe threads for holes here:

    Improvements to Onshape - June 27th, 2022 — Onshape

    The hole feature interface has changed since then, but ANSI based tapered pipe tap holes are found on the inch tab and ISO-7 based tapered pipe tap holes are found under the metric tab.  ISO-7 and older BSPT have now harmonized, so no need for separate standard approaches at this point.



    We do not yet offer tapered pipe threads on the external thread tool in part studios.

    We also do not yet offer options for parallel pipe threads for holes or external threads.

    The part I'm designing still needs external NPT threads.

    Yes, I noticed. Hence this topic.

    @ william_lucke
    Here are two files I have made that might help you. This is not a F.S. but is one way to create 3D pipe threads (not cosmetic and may not show in BOM).
    One is for female threads, and the other is male threads. I use these  like templates - deriving into a P.S. after creating the pipe (or fitting) using the right configuration (I made most common sizes, all NPT), then do a boolean subtract (it's a lot easier to derive now, with "insert to location").
    These models were made without allowing for fit tolerances and might not be "perfect", but do give a very close approximation. Make copies if you like, and move them to an easy to get to location - this is what I used to create my pipe fittings library without having to model every thread, every time. One word of caution, 3d threads will ruin drawings (to cluttered - use sparingly) but you might be able to get away with printing 3D threads (that, I haven't tried).
     One derive, then one boolean subtract, and it's done - instant threads. Just derive only the one tool named tap core or die core - (or something like that) and not all the sketches.
    Hope this might help.
