You use floor plan and section views to work with zones in the building model. You will need to activate the visibility for zones to view them.
In addition to using floor plan and section views, you can view the zone/space hierarchical relationships in the System Browser and in the Heating and Cooling Loads dialog.
You can view and work with zones in floor plan and section views. You select zones in a floor plan and section views the same way you select other components in Revit.
Zones (and spaces) associated with sliver spaces do not display in plan view.
You cannot view, create, or select zones in elevation or 3D views.
You can view the zone/space hierarchy in the System Browser. Spaces are organized according to the zones where they are assigned. There are two types of zones: Zones that you or someone else has created, and the Default zone. Spaces are initially assigned to the Default zone. Each space must be in a zone. When you create a zone, it displays separately from the Default zone in the System Browser listing. When you add spaces to a zone, the spaces are moved from the Default zone to a zone that you created. Eventually, all spaces in the model should be assigned to defined zones resulting in an empty Default zone.
To display zones in the System Browser, in the View bar, click Systems and select Zones.
To select a zone in the System Browser, click the zone while pressing CTRL. The selected zone highlights in red in the floor plan and section view. You can also right-click the zone, and select, show, or delete the zone, or view zone properties.
