True or False: Datums specify which surfaces on the part are to be used for inspection purposes.

The statement is true because datums are critical reference points or surfaces established on a part that serve as the basis for measurement and inspection. In GD&T, a datum represents an exact point, axis, or surface from which measurements are taken and tolerances are applied. By defining these datums, engineers and inspectors create a consistent framework for evaluating the part's features, ensuring that the inspection process is accurate and repeatable. Datums help ensure that parts will fit and function correctly, as they provide a standardized method for creating and validating the form, orientation, and location of features on the part. This is fundamental to the quality and interchangeability of manufactured components.
