Figure 143 — Spatial Element Type Predefined Type
If a custom value is needed to describe a spatial element type, the attribute ElementType may be used to define such custom type, where the PredefinedType is set to USERDEFINED.
Specific subtypes introduce additional attributes for User Identity.
NOTE Since the corresponding occurrences of IfcSpatialElementType do not have a Tag attribute, it is recommended not to use it here.
Figure 143 illustrates an instance diagram.
