[Mi...] Posted January 6 Share Posted January 6 Working on a profile call that is to a -Y- datum (6x pattern of holes). Anyway to apply MMC from the features as the datum? TIA. Link to comment Share on other sites More sharing options...
[Mi...] Posted January 7 Author Share Posted January 7 I was able to find this in the Y14.5 unsure if there is method to recreate this with Calypso software? The pattern of holes as a datum is fairly straight forward but the MMB bonus not so much... Link to comment Share on other sites More sharing options...
[Ja...] Posted January 8 Share Posted January 8 Good afternoon, If you have Calypso version 2022 or newer, it has a a GD&T engine. It is still in Beta, but I have tested the callout above using offline simulation, and it will calculate the profile with the datum shift on -Y-.

[Da...] Posted January 10 Share Posted January 10 I may be mis-understanding your question; I see a hole that is datum Y, but it's only 1 of 6 holes of that diameter. The positional callouts are ONLY to a 'primary' datum A, which I assume is the planar surface which these cylindrical features are perpendicular too? If that is the case, the callout is just a perpendicularity callout, to which I don't believe MMC can even be applied to since it is not a 'feature of size'. Perpendicularity does not change if the diameter varies, after all. If datum A is NOT the planar element (which is very unusual), then I don't have enough info to even have a clue. For the profile callout, what I read is that X is the 'planar' element, and the axis of Y is the perpendicular? So, maybe the cylinder locational discrepancy should be negated by the bonus tolerance and resulting datum shift , or else it will affect the profile? Frankly, this one makes my brain hurt......
