Datum Axis

Use the Datum Axis command to define linear reference objects to help you create other objects, such as datum planes, revolved features, extruded features, and circular patterns.

Datum axes can be associative or non-associative.

Associative datum axes

Associative datum axes reference curves, faces, edges, points, and other datums. You can create relative datum axes across multiple bodies.

Associative datum axes are listed in the Part Navigator as Datum Axis entries.

Non-associative datum axes

Non-associative datum axes do not reference other geometry. Use any of the datum axis methods to create fixed datum axes by clearing the Associative box in the Datum Axis dialog box.

Non-associative datum axes are listed in the Part Navigator as Fixed Datum Axis entries.
