Element to space boundary connection

Definition

The space boundary is a property of the space, but the elements (walls and slabs) that physically bound the space are not dependent on the spaces they bound. The concept of element to space boundary connection defines the connection between these elements from the viewpoint of the bounding element. Each boundary element (e.g. wall) has one relationship object (IfcRelSeparatesSpaces) that lists all space boundary objects that are aligned to that boundary element.
