IfcWindowPanelProperties: public Ifc4::IfcPreDefinedPropertySet¶
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 IfcWindowStyle 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 IfcWindowStyle.OperationType attribute, determines to which panel the IfcWindowPanelProperties apply. The IfcWindowPanelProperties are included in the list of properties (HasPropertySets) of the IfcWindowStyle. More information about the window panel can be included in the same list of the IfcWindowStyle using the IfcPropertySet for dynamic extensions.
HISTORY New entity in IFC Release 2.0, it had been renamed from IfcWindowPanel in IFC Release 2x.
IFC2x4 CHANGE Supertype changed to new IfcPreDefinedPropertySet.
Geometry use definitions The IfcWindowPanelProperties does not hold an own geometric representation. However it defines parameter, which can be used to create the shape of the IfcWindowStyle (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 panel is determined by the occurrence parameter assigned to the IfcWindow, which inserts the IfcWindowStyle. 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 176, 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.

Position of this panel within the overall window style.
Whether the optional attribute FrameDepth is defined for this IfcWindowPanelProperties.
Depth of panel frame, measured from front face to back face horizontally (i.e. perpendicular to the window (elevation) plane.
Whether the optional attribute FrameThickness is defined for this IfcWindowPanelProperties.
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.
Whether the optional attribute ShapeAspectStyle is defined for this IfcWindowPanelProperties.
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.
IFC2x4 CHANGE The attribute is deprecated and shall no longer be used, i.e. the value shall be NIL ($).
