Creates a new reference plane that is coincident to a selected part face or an existing reference plane. For example, you can define the new reference plane by selecting a part face (A), then specify the x-axis by selecting a part edge (B), and then specify the x-axis origin and direction by positioning the cursor near the end of the x-axis (C). A dynamic representation of the new reference plane is displayed.
Note:
When you run this command from the Home tab→Reference group, it creates a global reference plane. When you run it from a command bar, it creates a local reference plane for the current feature.
