[Cl...] Posted December 20, 2023 Share Posted December 20, 2023 I've never used this option before. Imagine a bowl sitting partly inside a very wide shallow cone (.050") section with a flat bottom. The cone is Datum -A- and there is a small OD cylinder at the 12:00 (Datum -B-). There are 4 slots equally spaced around the bowl. There is a position callout for each slot to A & B. It will not pass a type-1 gage rr. The position is currently being reported out 4 separate times. Can the bore pattern option be used in this scenario. If so, please elaborate on settings. Thank you in advance. Link to comment Share on other sites More sharing options...

[Cl...] Posted February 9 Author Share Posted February 9 Please sign in to view this quote. So I'm clear on this. If there are three features being evaluated for position back to two datums. A plane (Z) and a diameter (XY) (no tertiary clocking datum) I would uncheck rotation and translation? Allowing both datums to do so? Link to comment Share on other sites More sharing options...
