In Geometric Dimensioning and Tolerancing (GD&T), an orientation tolerance is used to control the
parallelism, perpendicularity, or angularity of a part feature with respect to
a frame of reference (defined by the datum references). This interactive, online course discusses the three different types of orientation tolerances:
Parallelism, Perpendicularity, and Angularity and how they are communicated in GD&T.
Describe the three different types of orientation tolerances: Parallelism, Perpendicularity, and Angularity
Describe how a tangent plane allows points on the feature to lie outside the tolerance zone
Describe how to interpret the associated tolerance zones for both planar and cylindrical features
Describe how orientation tolerances can interact with size tolerances to allow maximum flexibility for the manufacturer
