Geometric Dimensioning and Tolerancing (GD&T): Orientation Tolerances

By the end of this course you will be able to: 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
