Mass Floors At The Bottom Of A Mass; Creating Mass Floors - Autodesk 24000-000000-9860 - Revit Architecture - PC User Manual

Mass Floors at the Bottom of a Mass

To analyze a portion of a mass that occurs below the lowest mass floor, create a level and mass floor at the
bottom-most boundary of the mass. Otherwise, Revit Architecture does not include that portion in the
surface area or volume calculations for any mass floors. As an alternative, you can examine the Gross Surface
Area and Gross Volume parameters for the mass.
NOTE The Gross Surface Area includes the bottom surface of a mass. However, the combined exterior surface
areas of mass floors include the sides and top of the mass, but not its bottom surface.

Creating Mass Floors

1 If you have not already done so, add levels to the project.
