Kieth,
The most straight forward way to to tolerance the holes is to create several different DMIS tolerance definitions using the text editor. I find the drag and drop boxes tedious.
T(Dia1)=Tol/dia,-0.005,0.005
T(Dia2)=Tol/dia,-0.010,0.010
T(pos)=Tol/Pos,2d,.010,MMC,FA(Dat_A),MMC,FA(Dat_B),MMC,FA(Dat_C),MMC
$$ output first hole
Output/fa(holeA),TA(dia1)
Ouput/fa(holeA),TA(pos)
$$ output second hole
Output/fa(holeA),TA(dia2)
Ouput/fa(holeA),TA(pos)
Hope this helps.
