Space boundary

Version : 001 (18/06/00)

Definition

The concept of 'Space boundary' defines the boundaries of a space. The boundaries are a property of the space and they sit between the space object and the actual boundary objects (walls and slabs). The purpose of the space boundaries is to enable energy related calculations and they could in a very limited fashion be used for quantity takeoff. There is a lot to be improved in this concept so don't expect too much of it. There is a detailed paper that deals with just space boundaries.

The geometric representation of a space boundary is a single 3D polyline that can't have voids.
