[Ma...] Posted 9 hours ago Share Posted 9 hours ago Hi i have this sketch and i am dealing with symmetry callout with (M). My guess is using pattern of 6 symmetry points. Then using TruePosition. But problem is i can not find a way to enable MMR. Any hints? Part has 6 teeth symmetrical by 60° and width is determined by basic dimension of diameter ( red color ).

[Jo...] Posted 8 hours ago Share Posted 8 hours ago (edited) You could treat it as a position tolerance (actual symmetrie-point to ideal) with a non circular tolerance zone. Edit: Reading post again, this is what you allready tried? Edited 8 hours ago Link to comment Share on other sites More sharing options...

[Jo...] Posted 7 hours ago Share Posted 7 hours ago Replicated the situation and ... what to use as linear element of size? There is the witdh, but that is not the actually element the symmetrie or position is used on. So basiclly i would say you can not represent it like it is put in the drawing.

I can report TP for all or individual ones after i fix rotation, but anything above tolerance i can not calculate. Link to comment Share on other sites More sharing options...
[Jo...] Posted 7 hours ago Share Posted 7 hours ago Got another idea. Contruct circles from the intersection points of the teeth with the red circle and the symmetrie point of the pairs as center of the cirle. The ideal size and tolerance of the circles would be the same as the width. This way you got a elelement of size to use for postion with mmr, that in this scenario represents the same as the width.

[Ma...] Posted 7 hours ago Author Share Posted 7 hours ago Please sign in to view this username. I've tried circles. I did center of circle from symmetry point, radius from point ( one of them ) This allows me to finally see GD&T sizes, but it can not calculate 2point distance, so still no MMR in that. I wanted to use just 2 actual points to fit circle inside, but i can not do this either. Link to comment Share on other sites More sharing options...
[Jo...] Posted 6 hours ago Share Posted 6 hours ago You can`t use "Check Dimension (Independency Principle)" on the circles? Thats weird. Link to comment Share on other sites More sharing options...
[Ma...] Posted 6 hours ago Author Share Posted 6 hours ago (edited) Please sign in to view this username. While this circle is "refferenced" then i am getting no result with warning. Strange is, that in Calypso i can use Symmetry point ( not symmetry from points ) and it allows me to use MMC.

[Ra...] Posted 4 hours ago Share Posted 4 hours ago This may also help. https://carl-zeiss-industrial-metrology-llc.helpjuice.com/zeiss_inspect/zeissgom-inspect-check-position-gdt-position-tolerance/version/1?kb_language=en_US Link to comment Share on other sites More sharing options...
[Ma...] Posted 1 hour ago Share Posted 1 hour ago Please sign in to view this username. Thanks, but this is not helping in any way. I was trying at home in free version 26 - only option is using 2d lines, so perhaps making it shorter could help. Link to comment Share on other sites More sharing options...
