To Create Datum Axes
1. Click Refine Model > Axis.
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.
2. Use this dialog box to define the datum axis placement and properties.
3. Click OK.
The DATUM AXIS dialog box functions as it does in Creo Parametric. For more information on the dialog box, search the Part Modeling functional area of the Creo Parametric Help Center.
