The Datum toolset

A datum is a construction aid that helps you progress through the modeling process when the model itself does not contain the desired geometry. You use the Datum toolset to create these construction aids. This section explains how you use the Datum toolset to create and position datum points, axes, planes, and coordinate systems.
