Figure 276 — Project Declaration
The project provides a directory of object types and property templates contained within using declaration relationships.
NOTE The actual object occurrences used within the context of a project, such as walls, beams, air outlets, are assigned to a spatial hierarchy that is linked to the project using the aggregation hierarchy. See concept Spatial Decomposition for linking a spatial structure to the project.
HISTORY New concept template enabled by schema enhancements in IFC4.
Figure 276 illustrates an instance diagram.
