How to display the Reference Sets folder in the Part Navigator.

The Reference Sets folder can be displayed in the Part Navigator by enabling this setting in the Customer Defaults (File -> Utilities -> Customer Defaults).  It's located under Gateway -> Part Navigator. 'Display Reference Sets Folder = ON'.

You will need to restart NX for this setting to take effect.

The Reference Sets folder will only be displayed if the component or top level assembly contains model history.
