5.4.3.20 IfcElementAssemblyType

5.4.3.20.1 Semantic definition

The IfcElementAssemblyType defines a list of commonly shared property set definitions of an element and an optional set of product representations. It is used to define an element specification (i.e. the specific product information, that is common to all occurrences of that product type).

An element assembly type is used to define the common properties of a certain type of an element assembly that may be applied to many instances of that type to assign a specific style. An element assembly types (or the instantiable subtypes) may be exchanged without being already assigned to occurrences.

The occurrences of the IfcElementAssemblyType are represented by instances of IfcElementAssembly.
