Readers will learn:
1. Orientation controls; types, mathematical similarities; how they are used alone or as refinements of more powerful controls, the meaning of combined controls and how to read the controls as sentences.
2. Parallelism of surfaces, axes and centerplanes; what they mean, the tolerance zone configurations and how to measure them.
3. Coordinate measuring machines; least squares center vs. maximum inscribed cylinder center.
4. Tangent plane parallelism; tolerance zone configuration, what has to reside within it and how to measure it.
5. Perpendicularity of surfaces, axes and centerplanes; what they mean, the tolerance zone configurations and how to measure them.
6. Perpendicularity as a refinement of position.
7. How to read the geometric tolerances as sentences.
8. Angularity of surfaces, axes and centerplanes; what they mean, the tolerance zone configurations and how to measure them.
9. Tangent plane angularity; tolerance zone configuration and what has to reside within it.
10. Angularity of a line element.
11. Orientation of centerplane controls. The concept of unoriented, unlocated mating envelopes.
