Room Volume Enhancements - Autodesk 24000-000000-9860 - Revit Architecture - PC User Manual

When volume computation is turned on, Revit Architecture shows the actual boundaries used to compute
the volume of the room. These boundaries can include sloping elements, such as the walls, ceiling, and roof.

Room Volume Enhancements

When an existing project is opened in Revit Architecture 2009, it may show different numbers for room
volumes. These differences are due to enhancements that provide more accurate room volume calculations.
The software is now more flexible in the shapes of rooms for which it can compute volumes, and room
volumes are now computed to the wall face.
See Room Volume
Changes to Room Computation Height
The computation height is a defined height above the base level of a room. Revit Architecture measures the
perimeter of the room at this height, and uses this information when computing the room area and volume.
In previous releases, the room computation height was a project-wide setting. In Revit Architecture 2009,
the computation height is now a parameter of a level family. If needed, you can change this parameter. You
can also create multiple level families that use different computation heights. For example, you may want
to define one level family for stories and another level family for plenums. See
926.
NOTE Changing the computation height can affect the performance of Revit Architecture.
