|modifications||supertype||Changed from IfcPropertySetDefinition to IfcPreDefinedPropertySet|
A door panel is normally a door leaf that opens to allow people or goods to pass. The parameters of the door panel define the geometrically relevant parameter of the panel,
The IfcDoorPanelProperties are used to parametrically describe the shape and operation of door panels. The parametric definition can be added solely or additionally to the explicit shape representation of the door.
The IfcDoorType can define doors consisting of more then one panel. In this case, one instance of IfcDoorPanelProperties has to be included for each door panel. The PanelPosition attribute, in conjunction with the IfcDoorStyle.OperationType attribute, determines to which panel the IfcDoorPanelProperties apply. The IfcDoorPanelProperties are included in the list of properties , given by attribute HasPropertySets of the IfcDoorType. More information about the door panel can be included in the same list of the IfcDoorStyle using the IfcPropertySet for dynamic extensions.
The IfcDoorPanelProperties does not hold a geometric representation. However it defines parameters which can be used to create the shape of the door type(which is inserted by the IfcDoor into the spatial context of the project) as shown in Figure 1.
The parameters of the IfcDoorPanelProperties define a standard door panel, including (if given) a proportional width to define non-uniform double swing (or sliding, or folding) doors. The outer boundary of the panel is determined by the 'Profile' shape representation assigned to the IfcDoor, which inserts the IfcDoorType. It has to take the lining parameter into account as well.

HISTORY New entity in IFC2.0.
IFC4 CHANGE Supertype changed to new IfcPreDefinedPropertySet.
|1||GlobalId||IfcGloballyUniqueId||Assignment of a globally unique identifier within the entire software world.|
|2||OwnerHistory||OPTIONAL IfcOwnerHistory||Assignment of the information about the current ownership of that object, including owning actor, application, local identification and information captured about the recent changes of the object, |
> NOTE only the last modification in stored - either as addition, deletion or modification.
> IFC4 CHANGE The attribute has been changed to be OPTIONAL.
|3||Name||OPTIONAL IfcLabel||Optional name for use by the participating software systems or users. For some subtypes of IfcRoot the insertion of the Name attribute may be required. This would be enforced by a where rule.|
|4||Description||OPTIONAL IfcText||Optional description, provided for exchanging informative comments.|
|HasContext||SET [0:1] OF IfcRelDeclares FOR RelatedDefinitions|
|HasAssociations||SET [0:?] OF IfcRelAssociates FOR RelatedObjects||Reference to the relationship IfcRelAssociates and thus to those externally defined concepts, like classifications, documents, or library information, which are associated to the property definition.|
|DefinesType||SET [0:?] OF IfcTypeObject FOR HasPropertySets||The type object to which the property set is assigned. The property set acts as a shared property set to all occurrences of the type object.|
> NOTE The relationship between the IfcPropertySetDefinition and the IfcTypeObject is a direct relationship, not utilizing IfcRelDefinesByProperties, for maintaining compatibility with earlier releases of this standard.
> IFC4 CHANGE The cardinality has been changed from 0:1 to 0:? with upward compatibility for file based exchange.
|IsDefinedBy||SET [0:?] OF IfcRelDefinesByTemplate FOR RelatedPropertySets||Relation to the property set template, via the objectified relationship IfcRelDefinesByTemplate, that, if given, provides the definition template for the property set or quantity set and its properties. |
> IFC4 CHANGE New inverse relationship, change made with upward compatibility for file based exchange.
|DefinesOccurrence||SET [0:?] OF IfcRelDefinesByProperties FOR RelatingPropertyDefinition||Reference to the relation to one or many object occurrences that are characterized by the property set definition. A single property set can be assigned to multiple object occurrences using the objectified relationship IfcRefDefinesByProperties.|
> IFC4 CHANGE Inverse attribute renamed from PropertyDefinitionOf with upward compatibility for file-based exchange.
|5||PanelDepth||OPTIONAL IfcPositiveLengthMeasure||Depth of the door panel, measured perpendicular to the plane of the door leaf.|
|6||PanelOperation||IfcDoorPanelOperationEnum||The PanelOperation defines the way of operation of that panel. The PanelOperation of the door panel has to correspond with the OperationType of the IfcDoorStyle by which it is referenced.|
|7||PanelWidth||OPTIONAL IfcNormalisedRatioMeasure||Width of this panel, given as ratio relative to the total clear opening width of the door. If omited, it defaults to 1. A value has to be provided for all doors with OperationType's at IfcDoorStyle defining a door with more then one panel.|
|8||PanelPosition||IfcDoorPanelPositionEnum||Position of this panel within the door. The PanelPosition of the door panel has to correspond with the OperationType of the IfcDoorStyle by which it is referenced.|
|9||ShapeAspectStyle||OPTIONAL IfcShapeAspect||Pointer to the shape aspect, if given. The shape aspect reflects the part of the door shape, which represents the door panel.|
> DEPRECATION The attribute is deprecated and shall no longer be used, i.e. the value shall be NIL ($).
IfcRoot assigns the globally unique ID. In addition it may provide for a name and a description about the concept.
Ownership, history, and merge state is captured using IfcOwnerHistory.
