IfcRoofType: public Ifc4x3_rc1::IfcBuiltElementType¶
Definition from IAI: The element type IfcRoofType defines a list of commonly shared property set definitions of a roof and an optional set of product representations. It is used to define a roof 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 being an IfcMappedItem.
An IfcRoofTypeis used to define the common properties of a specific roof that may be applied to many instances of that type to assign a specific style. Building element types (or the instantiable subtypes) may be exchanged without being already assigned to occurrences.
The IfcRoofType can have common material (using the inverse relationship HasAssociations) or property set information (using HasPropertySets) assigned. If present, it does apply equally to all occurrences of the IfcRoofType. Property set information may be overridden at the occurrence.
HISTORY New entity in Release IFC2x Edition 4.
Identifies the predefined types of a roof element from which the type required may be set.
