Definitions:

Secondary Datum

A reference point, axis, or plane used in addition to the primary datum to provide further geometric control on a manufactured part.

Three-Plane Datum System

A geometric referencing system in drafting and engineering that defines a part's orientation and location using three mutually perpendicular planes.

Secondary Plane

An auxiliary plane, usually oriented perpendicularly or at an angle to the primary plane, used in design and analysis for additional reference.

Primary Plane

A basic geometric plane in a three-dimensional coordinate system, usually referred to as the XY, YZ, or ZX plane.
