Material conditions apply to features that can vary in size. At maximum material condition (, also known as MMC), a feature contains the maximum amount of material stated in the limits. At MMC, a hole has a minimum diameter, whereas a shaft has a maximum diameter. At least material condition (, 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. The third material feature condition, regardless of Feature Size (, also known as RFS), means a feature can be any size within the stated limits.
