Creating Mass Floors

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

   Mass floors are based on levels defined in the project. See Adding Levels.

2. Select the mass.

   You can select the mass in any type of project view, including floor plan, RCP, elevation, section, and 3D views.

3. Click Modify | Mass tabModel panel (Mass Floors).
4. In the Mass Floors dialog, select each level that needs a mass floor, and click OK.

   Initially, if you select a level that the mass does not intersect, Revit does not create a mass floor for that level. However, if you later resize the mass so that it intersects the specified level, Revit creates a mass floor on that level.

   

   Mass floors

After creating mass floors, you can do any of the following:

• Select a mass floor to view its properties (including area, perimeter, exterior surface area, and volume) and assign a usage. See Selecting Mass Floors and Mass Floor Properties.
• Tag mass floors. See Tagging Mass Floors.
• Create building floors from mass floors. See Creating Floors from Mass Floors.
