A floor plan divided into rooms, such as bedrooms,
a kitchen, a living room, and so on
An area is a subdivision of space within a building model, typically on a larger scale than individual rooms.
However, areas are not necessarily bounded by model elements. You can draw area boundaries or pick model
elements to use as boundaries.
When you add model elements, the area boundaries do not necessarily change automatically. You can specify
how area boundaries behave:
Some area boundaries are static. That is, they do not change automatically and must be changed manually)
Some area boundaries are dynamic. They stay connected with underlying model elements. If the model
elements move, the area boundaries move with them.
