Request a new Texture called a Hirth joint or Rosette

[Oldandretired]

When 2 surfaces with the radial v shaped cuts emanating from the center face each other they lock together and also provide a graduated control allowing the two faces to lock at a selected angle. This is called a Hirth joint. I just watched a Fusion expert, Kristian_laholm, create a Hirth joint. Yikes. https://youtu.be/6-xF2EYifCQ?is=JMAkzZxI2aEdOUHi

I have grabbed a couple of screen shots from the video. (The screen shots have a couple of captions from the audio of the video, not from me.)

His example seems very complicated. If several assumptions are made, then the only input would be a slider to input the number of spokes. You already have height input and if it protrudes in or out.

Thanks for your consideration.

In the past I was part of a change control board and before that we used Agile development. With AI being available, I couldn't confidently use a planning poker value of the difficulty creating the rosette/hirth pattern. Might be easy, might not.

I have printed 2 sets. incredibly easy!! I have one comment, I'm not sure I understand the reason for Length and Width instead of a diameter. Once the Length and Width do not match, the 'joint' no longer has rotational interlocking.

I suggest only a diameter slider.
All I can say is wow! Totally amazing.
As Rocky from 'Project Hail Mary' says, "amaze amaze amaze".

@Oldandretired Thanks for printing it and for the photos, great to see two working pairs! You're right about the size: a Hirth joint only interlocks when it's round, so separate Length and Width made no sense. I've changed it, it comes with the next update: the panel shows a single Diameter, every handle on the workplane changes that one diameter, and a joint that was already stretched becomes round again when you open the project.

Awesome. I feel like I'm back in my Quality Assurance days. Thanks again. I think this discussion is ready for closure. Agree?

[henmedia]

@Oldandretired Agreed, and thank you for the careful testing and the photos – that's the kind of QA I'd love on every feature. I'll close it now; the single Diameter comes with the next update.

@Oldandretired The single Diameter is out now in layerling 1.125.0. Reload layerling once to get it. Every handle on the workplane now changes just that one diameter, so the teeth always interlock all round.
