Currently, there is no possibility to see the level names on the minimap when using Walk/First Person tool in NWD files. They are only displayed when viewing Revit or specific instances of IFC files.
Navisworks files also have a levelled structure and the levels are read from the Revit files, so it would be a good idea to have them displayed on the minimap in BIM 360 Viewer using First Person tool too.
