The vertical extent of a space represents the space vertically from the base to the upper limit. Sometimes, you need to redefine the vertical extent of a space. This can occur for the following reasons:
- The upper limit of the space is specified incorrectly.
- The limit offset of the space is specified incorrectly.
- The space is referencing the wrong base level.
- The base offset of the space is specified incorrectly.
- The volume of the space is needs to be redefined.
- A change occurred in the specification.
