Defining the Lower Boundary of a Room
Together, the Level and Base Offset parameters define the lower boundary of a room.
In the room properties, the Level parameter is read-only. This parameter reflects the level of the plan view
in which you place the room. For example, if you place a room on a Level 2 floor plan, the Level parameter
for the room is Level 2.
Use the Base Offset parameter to indicate the distance between the base level and the lower boundary of
the room. To use the base level as the lower boundary, enter 0 (zero). To move the lower boundary above
the base level, enter a positive number. To move the lower boundary below the base level, enter a negative
number.
For example, in the following section view:
Room 1 has a Base Offset of 0. The lower boundary of the room starts at Level 1.
Room 2 has a Base Offset of 1000. The lower boundary of the room starts 1000 mm above Level 1.
Room 3 has a Base Offset of –500. The lower boundary of the room starts 500 mm below Level 1.
Changing the Room Height Graphically
In a section view, you can change the height of a room graphically by adjusting the upper and lower
boundaries of the room. When you change the boundaries of a room graphically, Revit Architecture
automatically updates the corresponding room parameters: Upper Limit, Limit Offset, and Base Offset. (See
Defining Room Height Parameters on page 930.)
