Does anyone know of a code to add the Bonus Tolerance to the true position value? I.E. if I have the call out TP DIA 0.010 (M) A B(M) C(M) where B and C are diameters each gaining a bonus of .005 in addition to the bonus tolerance of the diametrical feature being .002 so the total bonus would be .012 added to the .010 to give me a total tolerance of .022. Any help would be greatly appreciated.
One could use variable assignments inserted into generic features to simulate a true geometric couterpart. If that is what the OP was addressing with his query then I apologize for my brusk response. However, if the intent is to simulate the "wiggle" that an actual hard gage allows, then said programmer is misappropriating there skills in one of two ways:
1) they should develope there own metrology software or
2) allocate the greater portion of there days to gazing into there own navel
All i was saying is if the engineer has done his homework (calculations,stack ups) then the parts should fit together even with bonus tolerance. If they don't then he F'ed up ..... I write variables all the time to give the vendor the most tolerance allowed........
I am not trying to simulate a hard gage, rather simply trying to use all of the available tolerance the print allows.
The part is not being held by a fixture so the datums are being probed. It's v4.1 which under the true position dimension it has given me the option to add MMC from up to three datums, which it is calculating the bonus tolerance however it is only applying the bonus from the feature and one of the datums. So what I end up with is a part showing out of tolerance but yet I have bonus tolerance not being used from the second datum feature. I guess what really gets me is if the software isn't going to give me the total bonus tolerance when I select the datums why have it their in the first place.
