An explanation of the benefits of GPS and the difference between systematic GPS and traditional tolerancing.

The basic rules for dimensional tolerancing within GPS.

An introduction to geometrical tolerancing within GPS.

Understand how tolerance zones lock toleranced features

Tolerance zones are the building blocks of geometrical tolerancing. Learn about the shapes of tolerance zones and how to control their ability to move.

Datums and datum systems are the tools you use to constrain a tolerance zone for one feature on the component to one or more other features.

Learn how to estimate measurement uncertainty in accordance with the GUM method and the iterative PUMA method.
