Space

Version : 006 (23/04/01)

Definition

The concept of 'Space' is very central to the current implementations. Spaces are a good mechanism for giving the building a lot of structure - other objects can be contained by spaces, referenced by spaces or aligned to spaces. Using spaces in this manner is an important step from the CAD / geometry centered way of thinking to a way that is more information oriented. With spaces it would be possible to build a rich information model that doesn't contain any geometry at all (although this is not what we aim to do)

Although spaces are already very useful there are some quite important limitations. The space geometry is a singe extruded boundary polyline that can't have voids. It is not possible to model a large space that totally encloses another smaller space. The space boundaries are also quite limited and can't be used for e.g. material quantities if there is more than one surface material per space boundary.

The difference between 'Space occupancy' and 'Space occupant' might need some explanation.
