    This feature is really great - thanks a lot!

    As the comment above, I would like to model pipe threads (NPT, BSP) too. Is there a chance you can add these to your feature, or is there perhaps an other feature for pipe threads?

    I am trying to use ThreadLab for Internal threads, but it seems like it only "adds" threads to the hole. How can I get it to CUT threads? Thank you!!

    Fantastic work on this feature, B)
    Thank you so much for putting it out for everyone!

    One useful future feature would be the ability to set specific/offset the starting rotational position of modelled threads.

    Thanks for an amazing feature! 

    But i was having an issue when trying to create an 50mm internal thread

    LH thread worked fine, but not the RH thread. thought i would let you know.
    I was able to make it anyway by mirroring the part.

    This looks nice. But how do I use it? I'm not a programmer and I can't find a tutorial anywhere on what to do with the source code. :-(

    Here's a vid from their Youtube channel. I've been meaning to sit down and try some of this stuff for a while.

    I'm not sure if this is the place to mention it, but would there be a way to add the chamfer after the threads? The chamfer on a threaded stud works as it's implemented in a real world fastener or turned workpiece, but a threaded hole seems to add the threads after the chamfer, leaving a squared off thread start.



    I like to print threads and usually have to add a feature to make sure it actually gives you the taper on the thread start. It's something that's usually handled perfectly well with a note in most cases as it's something a machinist would do as a finishing step. If you're modeling the actual threads there's usually a reason though, and it's something I just prefer to have in my parts.

    antlu65  Great work, I'm going to use this. But here is something you might want to consider adding for us that use metal 3d threads.
    Both rolled threads and die cut threads have about 2 imperfect threads where the threads end at their full depth. One more revolve, at the base of the threads give a realistic look ( I've found that 2 times the pitch seems to give about the right amount of " tail-out " ).

    Is ThreadLab development dead? I would love to see the error on the hole callout resolved. 
  • MDesignMDesign Member Posts: 239 ✭✭✭

    I second this for internal threads. I added a ?12x1.25 hole and mistakenly assumed the thread lab tool would use the data and put the threads in correctly. To my surprise when the client asked to change the hole to m12x1.25. I had to do a double take and find the issue. To which thread lab ad did material making it basically m10

    This feature is great but the author/dev hasn't updated the document in a year and a half. Honestly I'd rather see it worked into an included feature.

    This is my biggest misgiving with using community featurescripts for commercial work. Sure it's nice that something exists, but reliability is essential for commercial applications and I'd really rather Onshape provide the tools I need to do my work, rather than tools I can use to make the tools I need to do my work, particularly for basics like threads.

    Onshape really needs to provide the functionality themselves so it comes with the assurance of stability and bug fixes - particularly as other updates are rolled out regularly to onshape.

    Appreciate everyone leaving feedback - apologies for not being in touch and not actively developing this. If I picked this project up again, I would re-write it with fewer 'accessory' features (e.g. thread callout, cosmetic threads, etc) and focus on modeled threads. @john_hauck's detailed post is especially instructive.

    @michael_zeagler , @Oliver_Couch , @MDesign , or anyone interested,

    Could you offer any comments on how your use cases align (or differ) with what @john_hauck described in his post? What are the most important features you would want to use in a modeled thread feature?

  • michael_zeaglermichael_zeagler Member Posts: 106 ✭✭✭

    @antlu65 no apology necessary! You don't owe us! Thanks for making the tool. It's great work.

    I personally use the tool for printed threads. Printing the threads into a part down to M3x.5 is really reliable and tends to be a lot like its own nylok nut. I generally have found my only wish to be the chamfering functionality I mentioned above.

    With Onshape implementing external cosmetic threads as time has gone on, I don't know if or when the last time I used it within threadlab. There's of course this feature request:

    actual cosmetic threads

    I'm not sure what progress there is on that front though.

    I'd really appreciate it if they'd put the same effect in the models that is in the drawings but we've all got to take what we get. They're always cooking back there.

    Thanks again for all your hard work. I looked into the featurescript and it sure looks like a ton of effort went into it.

    I'm fairly new with the thread lab tool. I use it for internal threads but I have to remember to override the diameter of the hole that the onshape hole feature creates because thread labs adds geometry to the face of the hole instead of cutting it out like a tap. Thankfully I use mostly metric threads and don't have to look up the diameter every time.

  • michael_zeaglermichael_zeagler Member Posts: 106 ✭✭✭

    I'd think if you were going to model the threads you could go with the drilled option instead of the tap drill.

    This is just one more reason they need to fold it in. One checkbox for "modeled" in the tapped hold dialogue would let you dispense with all the complexity.
