GEOMETRIC DIMENSIONING AND TOLERANCING (GD&T)Purpose is to describe the engineering intent of parts and assembliesUses symbols to specify geometric characteristics and dimensional requirementsCurrent GD&T standard: ANSI/ASME Y14.5M-2009Symbols for:Form and profile tolerances, orientation tolerances, location tolerances, runout tolerances

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&TBasic 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.
