Orientation tolerances control the alignment of features to datum features. Orientation
tolerances control the angularity, parallelism, and perpendicularity of features.
By the end of this course, you will be able to
• Define the tolerance zones for the perpendicularity of a plane or axis
• Define the tolerance zones for the angularity of a plane or axis
• Define the tolerance zone for the parallelism of planes or an axis
• Understand the application of the qualifying notation: “EACH RADIAL ELEMENT”
• Understand the application of a projected tolerance zone
• Understand the characteristic of a thread, or gear, to which a geometric tolerance
applies
