7.1.3.4 IfcWindowLiningProperties

DEPRECATED This definition will be removed in a future major release of this standard

7.1.3.4.1 Semantic definition

The window lining is the outer frame which enables the window to be fixed in position. The window lining is used to hold the window panels or other casements. The parameter of the IfcWindowLiningProperties define the geometrically relevant parameter of the lining.

The IfcWindowLiningProperties are included in the set of properties of IfcWindowType.HasPropertySets. More information about the window lining can be included in the same set of the IfcWindowType using another IfcPropertySet for dynamic extensions.

The IfcWindowLiningProperties does not hold a geometric representation. However it defines parameters which can be used to create the shape of the window type(which is inserted by the IfcWindow into the spatial context of the project) as shown in Figure 7.1.3.4.F. The parameters at the IfcWindowLiningProperties define a standard window lining, including (if given) a mullion and a transom (for horizontal and vertical splits). The outer boundary of the lining is determined by the 'Profile' shape representation assigned to the IfcWindow, which inserts the IfcWindowType.

7.1.3.4.3 Attributes

#	Attribute	Type	Description
IfcRoot (4)
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 is 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.
IfcPropertyDefinition (2)
	HasContext	SET [0:1] OF IfcRelDeclares FOR RelatedDefinitions	Reference to the relationship IfcRelDeclares and thus to the IfcProject or IfcProjectLibrary.
	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.
IfcPropertySetDefinition (3)
	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.

IfcWindowLiningProperties (12)
5	LiningDepth	OPTIONAL IfcPositiveLengthMeasure	Depth of the window lining (dimension measured perpendicular to window elevation plane).
6	LiningThickness	OPTIONAL IfcNonNegativeLengthMeasure	Thickness of the window lining as explained in the figure above. If LiningThickness value is 0. (zero) it denotes a window without a lining (all other lining parameters shall be set to NIL in this case). If the LiningThickness is NIL it denotes that the value is not available. IFC4-CHANGE Data type modified to be IfcNonNegativeLengthMeasure.
7	TransomThickness	OPTIONAL IfcNonNegativeLengthMeasure	Thickness of the transom (horizontal separator of window panels within a window), measured parallel to the window elevation plane. The transom is part of the lining and the transom depth is assumed to be identical to the lining depth. If the TransomThickness is set to zero (and the TransomOffset set to a positive length), then the window is divided vertically without a physical divider. IFC4-CHANGE Data type changed to IfcNonNegativeLengthMeasure.
8	MullionThickness	OPTIONAL IfcNonNegativeLengthMeasure	Thickness of the mullion (vertical separator of window panels within a window), measured parallel to the window elevation plane. The mullion is part of the lining and the mullion depth is assumed to be identical to the lining depth. If the MullionThickness is set to zero (and the MullionOffset set to a positive length), then the window is divided horizontally without a physical divider. IFC4-CHANGE Data type changed to IfcNonNegativeLengthMeasure.
9	FirstTransomOffset	OPTIONAL IfcNormalisedRatioMeasure	Offset of the transom centerline, measured along the z-axis of the window placement coordinate system. An offset value = 0.5 indicates that the transom is positioned in the middle of the window.
10	SecondTransomOffset	OPTIONAL IfcNormalisedRatioMeasure	Offset of the transom centerline for the second transom, measured along the x-axis of the window placement coordinate system. An offset value = 0.666 indicates that the second transom is positioned at two/third of the window.
11	FirstMullionOffset	OPTIONAL IfcNormalisedRatioMeasure	Offset of the mullion centerline, measured along the x-axis of the window placement coordinate system. An offset value = 0.5 indicates that the mullion is positioned in the middle of the window.
12	SecondMullionOffset	OPTIONAL IfcNormalisedRatioMeasure	Offset of the mullion centerline for the second mullion, measured along the x-axis of the window placement coordinate system. An offset value = 0.666 indicates that the second mullion is positioned at two/third of the window.
13	ShapeAspectStyle	OPTIONAL IfcShapeAspect	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 lining. IFC4-CHANGE The attribute is deprecated and shall no longer be used, i.e. the value shall be NIL ($).
14	LiningOffset	OPTIONAL IfcLengthMeasure	Offset of the window lining. The offset is given as distance along the y axis of the local placement (perpendicular to the window plane). IFC4-CHANGE New attribute added at the end of the entity definition.
15	LiningToPanelOffsetX	OPTIONAL IfcLengthMeasure	Offset between the lining and the window panel measured along the x-axis of the local placement. Should be smaller or equal to the LiningThickness. IFC4-CHANGE New attribute added at the end of the entity definition.
16	LiningToPanelOffsetY	OPTIONAL IfcLengthMeasure	Offset between the lining and the window panel measured along the y-axis of the local placement. Should be smaller or equal to the IfcWindowPanelProperties.PanelThickness. IFC4-CHANGE New attribute added at the end of the entity definition.

7.1.3.4.4 Formal propositions

Name	Description
WR31	Either both parameter, LiningDepth and LiningThickness are given, or only the LiningThickness, then the LiningDepth is variable. It is not valid to only assert the LiningDepth. NOTE A LiningDepth with NIL ($) value indicates a window style with a lining equal to the wall thickness. IFC4-CHANGE Rule corrected.
`NOT(EXISTS(LiningDepth) AND NOT(EXISTS(LiningThickness)))`
WR32	Either both parameter, FirstTransomOffset and SecondTransomOffset are given, or only the FirstTransomOffset, or none of both. It is not valid to only assert the SecondTransomOffset.
`NOT(NOT(EXISTS(FirstTransomOffset)) AND EXISTS(SecondTransomOffset))`
WR33	Either both parameter, FirstMullionOffset and SecondMullionOffset are given, or only the FirstMullionOffset, or none of both. It is not valid to only assert the SecondMullionOffset.
`NOT(NOT(EXISTS(FirstMullionOffset)) AND EXISTS(SecondMullionOffset))`
WR34	The IfcWindowPanelProperties shall only be used in the context of an IfcDoorType. NOTE The deprecated entity IfcWindowType is applicable as well.
