5.4.3.21 IfcFurnishingElementType

Type d'élément de mobilier
Ausstattung / Möbel - Typ

IfcFurnishingElementType 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 (the specific product information, that is common to all occurrences of that product type).

NOTE  The product representations are defined as representation maps (at the level of the supertype IfcTypeProduct, which gets assigned by an element occurrence instance through the IfcShapeRepresentation.Item[1] being an IfcMappedItem.

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

The occurrences of the IfcFurnishingElementType are represented by instances of IfcFurnishingElement (or its subtypes).
