class Ifc4::IfcPermeableCoveringProperties : public Ifc4::IfcPreDefinedPropertySet

This entity is a description of a panel within a door or window (as fillers for opening) which allows for air flow. It is given by its properties (IfcPermeableCoveringProperties). A permeable covering is a casement, such as a component, fixed or opening, consisting essentially of a frame and the infilling. The infilling is normally a grill, a louver or a screen. The way of operation is defined in the operation type. The IfcPermeableCoveringProperties are included in the list of properties (HasPropertySets) of the IfcWindowStyle or the IfcDoorStyle. More information about the permeable covering can be included in the same list of the window or door style using the IfcPropertySet for dynamic extensions. This particularly applies for additional properties for the various operation types

HISTORY New entity in IFC Release 2.0, it had been renamed from IfcPermeableCovering in IFC Release 2x.

IFC2x4 CHANGE Supertype changed to new IfcPreDefinedPropertySet.

Geometry use definitions The IfcPermeableCoveringProperties does not hold a geometric representation. However it defines parameters which can be used to create the shape of the IfcWindowStyle (which is inserted by the IfcWindow into the spatial context of the project), or of the IfcDoorStyle (which is inserted by the IfcDoor). The parameters at the IfcPermeableCoveringProperties define a standard permeable covering. The outer boundary of the panel is determined by the occurrence parameter assigned to the IfcWindow or IfcDoor. It has to take the lining parameter into account as well. The position of the permeable covering within the overall window or door is determined by the PanelPosition attribute.

As shown in Figure 174, the panel is applied to the position within the lining, as defined by the panel position attribute. The following parameters apply to that panel: FrameDepth, FrameThickness.

Public Functions

::Ifc4::IfcPermeableCoveringOperationEnum::Value OperationType() const

Types of permeable covering operations. Also used to assign standard symbolic presentations according to national building standards.

void setOperationType(::Ifc4::IfcPermeableCoveringOperationEnum::Value v)
::Ifc4::IfcWindowPanelPositionEnum::Value PanelPosition() const

Position of this permeable covering panel within the overall window or door type.

void setPanelPosition(::Ifc4::IfcWindowPanelPositionEnum::Value v)
bool hasFrameDepth() const

Whether the optional attribute FrameDepth is defined for this IfcPermeableCoveringProperties.

double FrameDepth() const

Depth of panel frame (used to include the permeable covering), measured from front face to back face horizontally (i.e. perpendicular to the window or door (elevation) plane.

void setFrameDepth(double v)
bool hasFrameThickness() const

Whether the optional attribute FrameThickness is defined for this IfcPermeableCoveringProperties.

double FrameThickness() const

Width of panel frame (used to include the permeable covering), measured from inside of panel (at permeable covering) to outside of panel (at lining), i.e. parallel to the window or door (elevation) plane.

void setFrameThickness(double v)
bool hasShapeAspectStyle() const

Whether the optional attribute ShapeAspectStyle is defined for this IfcPermeableCoveringProperties.

::Ifc4::IfcShapeAspect *ShapeAspectStyle() const

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 permeable covering.
