IfcCurtainWallType
Definition from IAI: The element type (IfcCurtainWallType)
defines a list of commonly shared property set definitions of a curtain
wall element and an optional set of product representations. It is used
to define a curtain wall specification (i.e. 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 curtain wall type is used to define the common properties of
a certain type of curtain wall that may be applied to many instances of
that type to assign a specific style. Curtain wall types may be
exchanged without being already assigned to occurrences.
The occurrences of the IfcCurtainWallType
are represented by instances of IfcCurtainWall.
