How do I mate a hirth joint?

ihor_gernaga

I haven't been able to mate a hirth joint correctly no matter what I choose to mate (point, plane or line). The one half has a rod that fits into a spindle and that mates fine which I mate first. Then I try to mate the hirth joint and it doesn't work. Search for hirth mate test on Public.

Thanks

Mates in Onshape are a bit different than in other traditional CAD systems, see this video https://www.youtube.com/watch?v=kK79nwi62Bg

@ihor_gernaga - HELLO!

Welcome to Onshape!

Onshape mating is a little different. In general, if you find yourself trying to add a SECOND mate to any two parts, 9 times out of 10 you dont need it!


Check out this document for how to do it!

Good luck!

Thank you Phillip. I still don't understand how one mate connector also aligns the teeth?

Just edit one of the mate connectors so it is rotated until teeth are aligned. Then all you need to use is a fasten mate. You can also add mate conectors in part studios utilising sketches which can also be helpful

Yes, what @brucebartlett said, explicit mate connectors declared in your partstudio are really helpful in cases like this.
