Area Definition (AREADE)

The Area Definition element is effectively a 3D volume that defines the 3D extents of a major architectural component; this may not be the same as the volume that encapsulates the elements within the major component.

The Area Definition can be used in several ways both by the user and the system. One of the primary functions of the Area Definition will be to identify which model elements are within the volume; this can then be used in a multitude of ways, from defining what elements are required in a view (2D or 3D) to producing inventories of rooms.

Ideally like the Boundary Line the volume should be directly owned by the major architectural component it relates too.
