Primary Datum

A reference point, axis, or plane from which dimensions are measured or a baseline for the construction of geometric features in drawings.

Geometric Tolerances

The limits of allowable variation in the shape and size of a part's geometry, including its form, orientation, and location, specified in engineering drawings.

Straightness

A condition where an element or line maintains a consistent path without deviation, typically applied in manufacturing to ensure parts are within specified tolerances.
