Create an inferred datum axis

This example shows how to create a datum axis using the Inferred type. NX determines the type of datum axis by what is selected to create it. When later edited, the dialog box will show the type NX selected — it will not be the Inferred type.

Procedure

1. Choose Home tab → Construction group → Datum Axis.
2. In the Datum Axis dialog box, from the Axis Type list, select Inferred.
3. In the Objects to Define Axis group, with Select Object active, select the objects you want to use to define the datum axis.
   • For this example: the edge of the hole was selected first and the face was selected next.
4. If your selections allow it, you can use Alternate Solution to define a different orientation.
   • In the example given, there are three alternate solutions available.
5. Click OK or Apply.
