What are Material condition modifiers?

• GD&T on holes (and shafts) provides a powerful tool for increasing inspection yield without trial-and-error fitting or binning.
• Used when the size of the feature interacts with its location.
• If ⓜ the symbol appears after the tolerance, then the specified tolerance holds only at maximum material condition.
• As the feature departs from MMC, the amount of departure can be added to the position tolerance.
• MMC is commonly used for clearance-type applications.
