Section view of a room when volume computation is turned off
When volume computation is turned on
When volume computation is turned on, Revit Architecture shows the actual boundaries used to compute
the volume of the room. These boundaries include sloping elements, such as the walls, ceiling, and roof.
Section view of a room when volume computation is turned on
In a section view, you can also check whether Revit Architecture is omitting parts of the room from its
volume computations. This may be caused by a combination of sloping walls and the computation height
that is defined for the corresponding level, or by other situations. See
Situations That Can Affect Room Volume Computations

Room-Bounding Elements

The following elements are bounding elements for room area and volume computations:
Walls (curtain, standard, in-place, face-based)
Roofs (standard, in-place, face-based)
Floors (standard, in-place, face-based)
Ceilings (standard, in-place, face-based)
