Circularity/Roundness as a Datum Feature
Circularity/Roundness as a Datum Feature
(OP)
Presently trying to figure out the relationship of a spherical profile (.001) GD&T referencing circularity (.001 as Datum A MMC). Does this mean that the profile tolerance follows the circularity tolerance at the circles' (±.001) maximum material condition? Does this imply a bonus? How does this differ from "form"?

These comments make no sense either! Show us a sketch of the part and its specifications.
