MMC/LMC (maximum material condition/least material condi-
tion) tolerance (circles, points arcs, spheres)
Use MMC/LMC tolerances for bores and bosses to specify nominal X, Y, and Z
positions for a selected feature, specify nominal diameter, specify nominal size,
specify bore or boss setting, and calculate pass/fail results. MMC/LMC
tolerancing factors true position bonus into its calculations.
