Thank you for this tutorial. I've been trying to make threads using the additive/subtractive helix method for the past month with no success (the helixes hate touching anything), yet I use this mod ONCE and it works as intended. Thank you so much, now all I gotta do is figure out the specs on this nut thread.

[@Adventuresincreation]

Excellent, I am glad it worked for you.

[@duller9430]

Thank you mr Aussie you have made my day with your simple tutorial! I hope you have a great day

[@Adventuresincreation]

You are welcome (I am English not Australian)

[@JLTSoft]

I didn't know about this workbench, either. How did I not know about this!?!? Good video.

[@Adventuresincreation]

It's a great workbench! 👍 now you know.

[@TexasExperience]

good stuff

[@Adventuresincreation]

Thanks! 😁

[@rodneysmith1750]

Brilliant, great video again!

[@Adventuresincreation]

Thank you! Cheers!

[@adrianoxenham362]

Great demonstration and instruction. Just need to find out how I can rotate objects

[@Adventuresincreation]

Have you tried the transform option?

[@adrianoxenham362]

@@Adventuresincreation you are taljing to a newbie.

[@iangrice5511]

Thank you!!! Very straightforward using your video 👍

[@Adventuresincreation]

Excellent, glad you like it Ian

[@chriskapis1690]

great video as all video

[@Adventuresincreation]

Thanks!

[@BillyJ57]

Very helpful Thanks so much I didn't know about that workbench. I vs 0.2.2 so fastener wb is even better.

[@Adventuresincreation]

You are very welcome!

[@The3DPrintingGrandad]

Is there a way to set tolerances fir the fasteners so they can be 3D printed? TIA, Larry

[@Adventuresincreation]

There is a setting in preferences for that

[@The3DPrintingGrandad]

@@Adventuresincreation Awesome! Just what I was looking for. I did a Google and a forum search and didn't find anything.

[@sh3riff]

Can this thread be done if you use a cylinder out of the Parts workbench?

[@Adventuresincreation]

Yes, I see no reason why that wouldn't work

[@VideoJocky1]

Good video. I need to make NPT taps and so far none of the tutorials I have seen deal with NPT tapered threads. Do you know how its done?

[@Adventuresincreation]

I don't know off the top of my head

[@АндрійРадист-о7б]

Good day. Can you explane how to use thread bit to milling this thread model?

[@Adventuresincreation]

Not sure quite what you mean, are you trying to machine a thread?

[@АндрійРадист-о7б]

@@Adventuresincreation Yes, I am trying to machine a thread but i don't know how it work.

[@Adventuresincreation]

@@АндрійРадист-о7б I am not sure you will be able to mill this thread. You can 3D print them. Creating threads on a mill is much more complicated.

[@АндрійРадист-о7б]

@@Adventuresincreation I am already print thread and today want to learn how to mill thread in FreeCAD. But I find only helix in path.

[@geojake]

I was following along, you mention creating multiple solids at the end, how do I avoid that? It's happening to me when tapping a M3 hole. If I set the tap size back to M6 (or set thread to false), no problem.

[@Adventuresincreation]

The M3 must be missing the main body and trying to create it in air

[@Enjoymentboy]

This was very helpful but I think either I am missing something or the workbench can't do what I want. Bear in mind I am new to FreeCAD and I'm hoping for some advice. I'm trying to create an odd SAE thread. 13/16 x 27 to be exact. I can see how to change the diameter but 13/16 isn't in the list and I can't see how I manually add a custom diameter nor how to set the TPI count. Is what I'm trying to do even possible with FreeCAD? Appreciated.

[@Adventuresincreation]

You can create the thread from scratch. You won't be able to do it with that workbench

[@Enjoymentboy]

@@Adventuresincreation That's what I was thinking. Appreciate the confirmation. I played around with it a bit this morning and I think I managed to fake my way through it by converting to a VERY close metric equivalent. Since this was a 3d printed part the PLA gave me a little wiggle room so thread accuracy didn't have to be spot on. In my case I made it as a 21mm x 0.775 thread and shockingly it worked out really well. More than "good enough" for my needs here.

[@HaJoSchatz]

Isn't there supposedly a gap between the bolt and the tap? When creating a tap as a boolean cut from the same part that also forms the bolt, then there won't be any gap and the two won't mate, no?

[@Adventuresincreation]

If you use the tap, it has the clearance built in, then if you use the rod they will mate. You can print them and try it. Make sure you have "printable" set in the settings.

[@QEngineering]

I haven't used this workspace yet, how is it for making 3D printed parts tolerances? 🍻

[@Adventuresincreation]

There's a setting to ensure the threats are printable

[@dmitrys777]

How create thread M13? This not available in Fasteners?

[@Adventuresincreation]

When adding the thread rod, selec the diameter parameter and choose custom (all the way at the bottom). Then make the thread diameter 13mm and choose your own pitch.
