7.1.3.2.1 Semantic definitions at the entity

A door panel is normally a door leaf that opens to allow people or goods to pass. The parameters of the door panel define the geometrically relevant parameter of the panel,

The IfcDoorPanelProperties are used to parametrically describe the shape and operation of door panels. The parametric definition can be added solely or additionally to the explicit shape representation of the door.

The IfcDoorType can define doors consisting of more then one panel. In this case, one instance of IfcDoorPanelProperties has to be included for each door panel. The PanelPosition attribute, in conjunction with the IfcDoorStyle.OperationType attribute, determines to which panel the IfcDoorPanelProperties apply. The IfcDoorPanelProperties are included in the list of properties , given by attribute HasPropertySets of the IfcDoorType. More information about the door panel can be included in the same list of the IfcDoorStyle using the IfcPropertySet for dynamic extensions.

The IfcDoorPanelProperties does not hold a geometric representation. However it defines parameters which can be used to create the shape of the door type(which is inserted by the IfcDoor into the spatial context of the project) as shown in Figure 1.

The parameters of the IfcDoorPanelProperties define a standard door panel, including (if given) a proportional width to define non-uniform double swing (or sliding, or folding) doors. The outer boundary of the panel is determined by the 'Profile' shape representation assigned to the IfcDoor, which inserts the IfcDoorType. It has to take the lining parameter into account as well.

 

panel 1 The depth of the panel (swinging, double-acting, and sliding panels) is defined by the PanelDepth parameter.
  • PanelDepth
panel 2 For door operation types that include more than one panel, the width of (at least) one panel is given by a normalised ratio measure. It determines the width of that panel, which is defined as a ratio of the overall width of the door opening.
  • PanelWidth

HISTORY  New entity in IFC2.0.

IFC4 CHANGE  Supertype changed to new IfcPreDefinedPropertySet.

7.1.3.2.1 Attributes

# Attribute Type Description
IfcRoot
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 in 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
HasContext SET [0:1] OF IfcRelDeclares FOR RelatedDefinitions
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
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.
DefinesOccurrenceSET [0:?] OF IfcRelDefinesByProperties FOR RelatingPropertyDefinitionReference 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.
IfcPreDefinedPropertySet
IfcDoorPanelProperties
5 PanelDepth OPTIONAL IfcPositiveLengthMeasure Depth of the door panel, measured perpendicular to the plane of the door leaf.
6 PanelOperation IfcDoorPanelOperationEnum The PanelOperation defines the way of operation of that panel. The PanelOperation of the door panel has to correspond with the OperationType of the IfcDoorStyle by which it is referenced.
7 PanelWidth OPTIONAL IfcNormalisedRatioMeasure Width of this panel, given as ratio relative to the total clear opening width of the door. If omited, it defaults to 1. A value has to be provided for all doors with OperationType's at IfcDoorStyle defining a door with more then one panel.
8 PanelPosition IfcDoorPanelPositionEnum Position of this panel within the door. The PanelPosition of the door panel has to correspond with the OperationType of the IfcDoorStyle by which it is referenced.
9 ShapeAspectStyle OPTIONAL IfcShapeAspect Pointer to the shape aspect, if given. The shape aspect reflects the part of the door shape, which represents the door panel.

> DEPRECATION  The attribute is deprecated and shall no longer be used, i.e. the value shall be NIL ($).

7.1.3.2.3 Definitions applying to General Usage

7.1.3.2.3.1 Identity

IfcRoot assigns the globally unique ID. In addition it may provide for a name and a description about the concept.

7.1.3.2.3.2 Revision Control

Ownership, history, and merge state is captured using IfcOwnerHistory.
