Controls the shape of a feature regardless of its location or orientation. Parallelism, Perpendicularity, Angularity Controls the rotation of a feature relative to a datum. Location Position, Concentricity, Symmetry
The standard organizes geometric controls into several functional categories to manage different aspects of part geometry: Typical Controls Straightness, Flatness, Circularity, Cylindricity Dimensioning and Tolerancing ASME Y14.5M-1994
The standard relies on several fundamental rules that guide how dimensions and tolerances are applied: Controls the shape of a feature regardless of
