Hi there,

Question came about the possibility to use a composite position tolerance where the tolerance value in the upper segment uses an LMC modifier, and the lower segment tolerance value uses an MMC modifier. I have not included an specific example, but we’re just wondering about the validity of such control. Datum references in both segments are specified at RFS (using ASME Y14.5M-1994).

There is a similar example question No. 4 in exercise 19-1 of Alex’s Advanced Concepts of GD&T book, but there is no answer to this exercise question.

Thanks for your help!
