|Type d'élément spatial|
|Räumliches Element - Typ|
defines a list of commonly shared property set definitions of a
spatial structure element and an optional set of product
representations. It is used to define a spatial element
specification (the specific element information, that is
common to all occurrences of that element 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 being an
A spatial element type is used to define the common properties
of a certain type of a spatial structure element that may be
applied to many instances of that type to assign a specific
style. Spatial element types (i.e. the instantiable subtypes) may
be exchanged without being already assigned to occurrences.
NOTE The spatial element types are often used to
represent catalogues of predefined spatial types for shared
attributes, less so for sharing a common representation
The occurrences of subtypes of the abstract
IfcSpatialElementType are represented by instances of
subtypes of the abstract IfcSpatialElement.

The type denotes a particular type that indicates the object further. The use has to be established at the level of instantiable subtypes. In particular it holds the user defined type, if the enumeration of the attribute 'PredefinedType' is set to USERDEFINED.
