Definitions:

Secondary Datum

A reference point, line, or surface used in conjunction with primary datums to establish a part’s orientation or location for measurement and manufacturing.

Geometric Tolerances

Specifications on a technical drawing, denoted by symbols, that dictate the allowable deviation in the form, orientation, location, and profile of a part's features.

Datums

Datums are reference points, lines, or surfaces on an object against which measurements are made, serving as a foundation for geometric tolerances in engineering drawings.

Datum Feature Symbol

A symbol used in geometric dimensioning and tolerancing to specify a reference for measurements.
