GEOMETRIC DIMENSIONING AND TOLERANCING (GD&T)
•Uses symbols to specify geometric characteristics and dimensional requirements
•Current GD&T standard: ANSI/ASME Y14.5M-1994
•Symbols for:
•Form and profile tolerances
•Orientation tolerances
•Location tolerances
•Runout tolerances

•Feature control frame

•MMC – Maximum Material Condition
•LMC – Least Material Condition
•ISO standard of preferred metric limits and fits: In the dimension 16h11, the tolerance zone is specified by a letter and a number, I.e. h11. An uppercase letter indicates that the tolerance applies to the hole; a lowercase letter indicates the tolerance applies to the shaft.

GD&T•Basic Dimension: Theoretically exact, untoleranced dimensions that specify the perfect location, size, shape, or angle of a feature.
•Basic dimensions are identified by enclosing the dimension in a box.
•Basic dimensions specify theoretically exact value from which variations are defined through feature control frames as well as toleranced features and notes.
•General tolerances do not apply to basic dimensions.
