Revit uses room boundaries when computing the area, perimeter, and volume of a room.
To check room boundaries in plan views and section views, you can select rooms or change visibility/graphic settings for the view.
Topics in this section
About Room-Bounding Elements
To indicate that an element should be used to define the boundaries of a room for room area and volume computations, you must specify that the element is room-bounding.
About Room Boundaries in Linked Models
When you link Revit models together, by default Revit does not recognize room-bounding elements in the linked model.
About Rooms in Plan Views
Use a plan view to visually check the outer boundaries (perimeter) of a room.
Make an Element Room Bounding
When you turn on the Room Bounding parameter for a model element, Revit uses the element as a boundary for a room. This boundary is used to compute the area and volume of the room.
Add a Room Separation Line
When room-bounding elements do not exist at the desired boundary of a room, add a separation line to help define the room.
Control the Visibility of Room Separation Lines
By default, room separation lines are visible in plan views and 3D views. Use a Visibility/Graphics setting to change their visibility in a view.
Use Room Boundaries in a Linked Model
When linking models together, you can make the host project recognize the Room Bounding parameter of elements in the linked model.
