See attached picture. Where does the tolerance (circled in red) come from? I know it has something to do with MMB on Datum B, but can't quite figure out how it ties in...
Notice that you have circle-M on the datum.
This gives you datum shift as that datum departs from MMB, Max Material Boundary.
That value you circled is actually the amount of datum shift that was used in the calculation of that dimension. Further over is a larger value that tells us how much was left over.
I know it is not clear. Once I figure out a better way to report it I'm putting in a request to change it.
