Name Description
Constraints
Level The base level on which the room resides. A read-only value. See Defining the Lower Boundary of a Room.
Upper Limit The level from which to measure the upper boundary of the room. See Defining the Upper Boundary of a Room.
Limit Offset The distance at which the upper boundary of the room occurs, measuring from the Upper Limit level. Enter a positive number to go above the Upper Limit level, or enter a negative number to go below it. Enter 0 (zero) to use the level specified for the Upper Limit. The default is 10’ (4000 mm). See Defining the Upper Boundary of a Room.
Base Offset The distance at which the lower boundary of the room occurs, measuring from the base level (defined by the Level parameter). Enter a positive number to go above the base level, or enter a negative number to go below it. Enter 0 (zero) to use the base level. The default is 0. See Defining the Lower Boundary of a Room.
Dimensions
Area The net area computed from the room-bounding elements. A read-only value. See Room Area.
Perimeter The perimeter of the room. This is a read-only value. See Room Area.
Unbounded height The largest potential height of the room, based on the room height parameters: Level, Upper Limit, Limit Offset, and Base Offset. This value is read-only. See Defining Room Height. (The room’s actual height may be changed by room-bounding elements, such as intervening floors and roofs. See Considering Ceilings and Floors in Room Volume Computations.)
Volume The volume of the room when volume computation is enabled. See Room Volume. A read-only value.
Identity Data
Number An assigned room number. This value must be unique for each room in a project. Revit Architecture warns you if the number is already used but allows you to continue using it. (See Reviewing Warning Messages or Warnings for Selected Elements.) Room numbers are assigned sequentially. See Creating Sequential Room Number Tags.
Name The room name, such as Conference Room or Kitchen.
Comments User-specified information about the room.
Occupancy Type of occupancy for the room, such as Retail.
Department Department for which the room will be used.
Base Finish Finish for the base.
Ceiling Finish Finish for the ceiling, such as stucco.
Wall Finish Finish for the wall, such as painted.
Floor Finish Finish for the floor, such as carpeting.
Occupant Name of the person, group, or organization that will use the room.
Phasing
Phase The project phase to which the room belongs. A read-only value based on view properties. See Phase-Specific Rooms and Boundaries.
