A window panel is a casement, that is, a component, fixed or opening, consisting essentially of a frame and the infilling. The infilling of a window panel is normally glazing. The way of operation is defined in the operation type.
The IfcWindowPanelProperties are used to parametrically describe the shape and operation of window panels. The parametric definition can be added solely or additionally to the explicit shape representation of the window.
The IfcWindowType can define windows consisting of more then one panel. In this case, one instance of IfcWindowPanelProperties has to be included for each window panel. The PanelPosition attribute, in conjunction with the IfcWindowType.OperationType attribute, determines to which panel the IfcWindowPanelProperties_apply. The _IfcWindowPanelProperties are included in the list of properties (HasPropertySets) of the IfcWindowType. More information about the window panel can be included in the same list of the IfcWindowType using the IfcPropertySet for dynamic extensions.
The IfcWindowPanelProperties does not hold an own geometric representation. However it defines parameter, which can be used to create the shape of the IfcWindowType (which is inserted by the IfcWindow into the spatial context of the project). The parameters at the IfcWindowPanelProperties define a standard window panel. The outer boundary of the lining is determined by the 'Profile' shape representation assigned to the IfcWindow, which inserts the IfcWindowType. It has to take the lining parameter into account as well. The position of the window panel within the overall window is determined by the PanelPosition attribute.
As shown in Figure 220.127.116.11.A, the panel is applied to the position within the lining as defined by the panel position attribute. The following parameter apply to that panel: FrameDepth, FrameThickness.
Assignment of a globally unique identifier within the entire software world.
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,
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.
Optional description, provided for exchanging informative comments.
|HasContext||SET [0:1] OF IfcRelDeclares FOR RelatedDefinitions||
No description available.
|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.
|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.
|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.

Types of window panel operations. Also used to assign standard symbolic presentations according to national building standards.
Position of this panel within the overall window style.
Depth of panel frame, measured from front face to back face horizontally (i.e. perpendicular to the window (elevation) plane.
Width of panel frame, measured from inside of panel (at glazing) to outside of panel (at lining), i.e. parallel to the window (elevation) plane.
Optional link to a shape aspect definition, which points to the part of the geometric representation of the window style, which is used to represent the panel.
Ownership, history, and merge state is captured using IfcOwnerHistory.
IfcRoot assigns the globally unique ID. In addition it may provide for a name and a description about the concept.
