How can you tell which reference set is currently displayed?

The reference set currently displayed can be identified by looking for the reference set name in the Assembly Navigator. In NX, the Assembly Navigator is designed to provide a clear view of the components and their relationships within an assembly, including the active reference set. Each reference set is listed, and the currently active one is typically highlighted or indicated prominently. This feature is crucial because it allows users to quickly determine which set of references is being used for the assembly work, facilitating better management of components and their visibility during design tasks.

Other options may provide useful information or context in different scenarios, but they do not specifically focus on identifying the reference set as effectively as the Assembly Navigator does. The command bar might display commands or notifications relevant to the active tools being used but does not indicate the reference set directly. The model workspace reflects the geometry of the displayed parts but doesn't specify which reference set is active. The properties dialog provides details about selected objects but is less focused on the active reference set and is more oriented towards the specifics of individual components or features.
