Re: Pipe ( NPT ) Threads again
@rick_randall curiosity got the better of me and I was able to mock up a feature that instantiates your model. Check it out! I linked it to a copy of your part studio since I needed to tweak a few things, but think in the long run it'd be better for it to be linked to yours since you're more likely to maintain the configured models better. Let me know if you're interested and I can help make that happen.
Re: Pipe ( NPT ) Threads again
@rick_randall great configured models! btw, you can also place and boolean multiple of these at once using the Super Derive custom feature. It is also possible to create a custom feature that uses these as a basis and derives them, places them, and does the boolean subtract. That feature could have inputs that match all of the configuration inputs.
Re: oploft connections
What does it look like if you add a debug point to the 0 parameter on each circle? I'm curious if they are lined up or not.
Re: Chamfer Text Embossed onto Cylinder
Images would help a lot, but in similar situations I've used Draft set to Parting Line with some success. Here's an example. I used a separate draft feature per letter since they don't share a pull direction. https://cad.onshape.com/documents/18c5f5f2106d341883578e39/w/d66da98662f95ea067ca0ee7/e/cf7518b60b641604c6d9227c
Re: CAD Challenges App
This CAD Challenges app sounds like an amazing resource for students to build and refine their 3D modeling and design skills! Practicing with section views, auxiliary views, and dimension interpretation not only strengthens technical proficiency but also prepares students for certifications like the Certified Onshape Associate exam. A great way to make learning CAD engaging and interactive—perfect for developing real-world design expertise!
Re: Pipe ( NPT ) Threads again
@Oliver_Couch - You are correct about Dim "AM" (absolute minimum) being Dim "L4". My source was an older (1920's) American Machinists Handbook, but I could have typo-ed that one. And thank you for bringing that to my attention, I will correct that oversight. After looking at the table above, most Dims are very close, but do not match exactly, and I'm going to let them fall into the "tolerance" category. Please let me know If there are any other issues that need looking at. Happy to make any corrections - or feel free to use my workflow to create your own "thread cores" using any standard that you need (this would give you absolute control over accuracy).
Edit, Have made some corrections - you might want to update to latest versions.
2nd edit - Some further explanation - these 3D threads are only supposed to be "representations" to check for basic form and fit, and would normally only be noted with a "call out" on a drawing. A pipe or fitting, generally, is a buy-out item, and the need to detail the thread on a drawing is unnecessary (only the tool & die maker, that makes the tooling needs to worry about this).
As for 3D printing, care should be taken to insure proper clearances, but I think parts made with these "thread cores" could be used as long as the proper offset is used (once again, I have never tried this - and didn't make any allowances for it).
Re: Detail look correct, but 9 features failed to regenerate
BTW, if you want the same chamfer on the edges of the part, and all the holes, you can pick the face of the top and bottom of the part. Then you would get a chamfer on everything with only two clicks.
Re: Gewinde!
On the topic of threads and it 'not doing anything' I think at least some of the problem is that in the 3D model there is no indication at all that a thread has been applied. Could a solution be borrowed from solid works where it places a broken circle, as per eng drawing convention, on the top face to indicate a cosmetic thread?
Re: Pipe ( NPT ) Threads again
@riley_smith120 - @Oliver_Couch
Glad to hear you guys liked those models. The work flow was to make the tools once, then use that tool over and over. The real advantage is the time saving factor, and maybe even a little less meta-data, compared to modeling threads in every part. Once again I will caution about 3D threads in drawings - just a few can create a mess. My intention was to help a friend create images for a build manual - and I was after realism. Anyone with F.S. skills could probably automate this process if they wanted.
Cheers - Rick
