Revit LT uses the height of a room to compute its volume. You can specify the height of a room in the following ways:
- Define room height parameters. In a plan or section view, select the room and edit its properties. The Upper Limit, Limit Offset, Level, and Base Offset parameters define the height of the room.
- Change the room height graphically. After adding a room to a plan view, open a section view that shows the room. In the section view, you can select the room and use controls to adjust the upper and lower boundaries of the room. See Rooms in Section Views.
