Datum Axis
Use Refine Model > Axis to create datum axes. You may need datum axes on your model to create a number of Creo Simulate modeling entities. For example, you can use a datum axis when designing a cyclic symmetry constraint or defining a coordinate system.
If your model is an assembly then the Select a Component dialog box opens. The top level assembly is selected by default and displayed in the collector. Select the component for which you want to create a datum axis. Click OK. The DATUM AXIS dialog box opens.
For more information on creating datum axes, search the Part Modeling functional area of the Creo Parametric Help Center.
When you create datum axes, Creo Simulate treats the axes as simulation features. Simulation features are not visible or accessible when you return to Creo Parametric unless you promote them.
