Acme Thread in SolidWorks

- A few students in my Parametric Modeling class asked about cutting an Acme thread in SolidWorks. The thread tool in SolidWorks doesn't have an Acme option, so you have to do it by creating a helix at the proper pitch and a profile of either the thread or the tool that would cut a thread.
Thanks. Making that ref. plane normal to the helix was the trick. very nice expiation. I agree with @mostsoot it does sound like a 3D printer printing a curved or circular outer/inner wall. Ha. ("inexpensive" stepper motor resonance is pretty obvious...) I actually thought the same when I first watched your video... :)
Anyway, the dimensions on your trapezoid are for LMC (largest hole) conditions? Nominally, that root depth is 0.5 * pitch (0.5 * 1/6 = 0.0833 - you use 0.0933)?
You're welcome. I am not sure what that noise is, and I agree that it sounds like a 3D printer. I have 10 printers, but they are at work. I made this video in my home office, where I do not have a printer. The only thing I have in here that makes noise is two EGO battery chargers, but I wouldn't have made a video while charging those batteries because it is very noisy. Perhaps some radio frequency problem?
I found some differing dimensions for acme threads. I think I used the Machinery's Handbook, but can't remember anymore and it may have been a typo. Obviously, you could modify those dimensions. The purpose of the video was just to show a student how to create a thread using a profile and a helix. The thread tool in SolidWorks doesn't always give a true thread in my experience, so when I do want to create one for 3D printing something with a thread, I usually create the thread this way and reduce the size of an external or increase the size of an internal thread and modify it if it doesn't work.
I followed this exact procedure, and it worked great. However, I have 19 more of the exact same holes I want the same exact thread in. What’s a slick way to apply what I’ve done to all 20 total holes?
If the holes are applied as a pattern you can apply these features to the pattern by moving it before you created the hole pattern.
It is possible to create a custom thread profile, which would make things a little more streamlined if the holes were not placed as a pattern. Here is a good description of how:

It may be possible to save the threaded hole as a library feature, but I've never tried it, so I can't vouch for it. Here's a link to a description on saving library features though. I will try it myself if I get some time.

is that 3D printer sound on background :)
I hadn't noticed the background noise, but no, it is a charger for a EGO battery for my snow blower (or chainsaw, or hedge trimmer, or string trimmer, or lawn mower -- I am a fan).

I made this in my home office, where the only printer is a laser. Whatever it sounds like, it isn't a 3D printer.
