Together, the Upper Limit and Limit Offset parameters define the upper boundary of the room.
Note: If room-bounding elements intersect the upper limit offset, those elements form the upper boundary instead. (See About Ceilings and Floors in Room Volume Computations.)
For example, suppose a room starts at Level 1. To indicate that it should extend upward 4000 mm above Level 2, specify an Upper Limit of Level 2 and a Limit Offset of 4000 mm. By default, the Limit Offset is the distance between levels (10’ or 4000 mm).
- Room 1 has an Upper Limit of Level 1 and a Limit Offset of 4000.
- Room 2 has an Upper Limit of Level 1 and a Limit Offset of 3000.
- Room 3 has an Upper Limit of Level 2 and a Limit Offset of 4000.
- Room 4 has an Upper Limit of Level 2 and a Limit Offset of 3500.
