class Ifc4::IfcWindowLiningProperties : public Ifc4::IfcPreDefinedPropertySet

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.

NOTE The IfcWindowLiningProperties shall only be applied to construct the 3D shape of a window, if the attribute IfcWindowStyle.ParameterTakesPrecedence is set TRUE.

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

HISTORY New Entity in IFC Release 2.0. Has been renamed from IfcWindowLining in IFC Release 2x.

IFC2x4 CHANGE The following attributes have been added LiningOffset, LiningToPanelOffsetX, LiningToPanelOffsetY. The attribute ShapeAspectStyle is deprecated and shall no longer be used. Supertype changed to new IfcPreDefinedPropertySet.

Geometry use definitions The IfcWindowLiningProperties does not hold a geometric representation. However it defines parameters which can be used to create the shape of the window style (which is inserted by the IfcWindow into the spatial context of the project) as shown in Figure 175. 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 occurrence parameter assigned to the IfcWindow, which inserts the IfcWindowStyle.

The lining is applied to all faces of the opening reveal. The parameter are:

LiningDepth LiningThickness LiningOffset LiningToPanelOffsetX LiningToPanelOffsetY

NOTE Parameters added in IFC2x4.

Inner side is defined as the direction of the window panel opening operation.

If the OperationType of the window style is

DoublePanelVertical (shown) TriplePanelBottom TriplePanelTop TriplePanelLeft TriplePanelRight

the following additional parameter apply:

MullionThickness FirstMullionOffset - measured as offset to the Z axis (in XZ plane)

If the OperationType of the window style is

DoublePanelHorizontal TriplePanelBottom TriplePanelTop TriplePanelLeft TriplePanelRight

the following additional parameter apply

TransomThickness FirstTransomOffset measured as offset to the X axis (in XZ plane)

If the OperationType of the window style is

TriplePanelVertical

the following additional parameter apply

SecondMullionOffset

If the OperationType of the window style is

TriplePanelHorizontal

the following additional parameter apply

SecondTransomOffset

NOTE

All offsets are given as a normalized ratio measure.

Public Functions

bool hasLiningDepth() const

Whether the optional attribute LiningDepth is defined for this IfcWindowLiningProperties.

double LiningDepth() const

Depth of the window lining (dimension measured perpendicular to window elevation plane).

void setLiningDepth(double v)
