Material conditions apply to features that can vary in size. At maximum material condition (symbol M, also known as MMC), a feature contains the maximum amount of material stated in the limits. At MMC, a hole has minimum diameter, whereas a shaft has maximum diameter. At least material condition (symbol L, also known as LMC), a feature contains the minimum amount of material stated in the limits. At LMC, a hole has maximum diameter, whereas a shaft has minimum diameter. Regardless of feature size (symbol S, also known as RFS) means a feature can be any size within the stated limits.
