When MMC or LMC is not specified with a geometric tolerance for a feature of size, the tolerance applies regardless of feature size.
Geometric Tolerance
A set of standards that defines the allowable shape, orientation, and positioning variations for features on manufactured parts.
MMC
Maximum Material Condition; a feature size where it contains the maximum amount of material yet still meets the part's tolerance specifications.
LMC
Least Material Condition, a feature of size symbol that denotes the tolerance condition of a part when it contains the least amount of material within specified limits.
