7.1.3.1 IfcDoorLiningProperties

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

7.1.3.1.1 Semantic definition

The door lining is the frame which enables the door leaf to be fixed in position. The door lining is used to hang the door leaf. The parameters of the door lining define the geometrically relevant parameter of the lining.

The IfcDoorLiningProperties are included in the list of properties of IfcDoorType.HasPropertySets. More information about the door lining can be included in the same list of the IfcDoorType using another IfcPropertySet for dynamic extensions.

The IfcDoorLiningProperties does not hold its own 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 described below. The parameters of the IfcDoorLiningProperties define a standard door lining, including (if given) a threshold and a transom. The outer boundary of the lining is determined by the 'Profile' shape representation assigned to the IfcDoor, which inserts the IfcDoorType.

lining 1
Figure 7.1.3.1.A

The lining is applied to the left, right and upper side of the opening reveal. The parameters are:

  • LiningDepth, if omitted, equal to wall thickness - this only takes effect if a value for LiningThickness is given. If both parameters are not given, then there is no lining.
  • LiningThickness
  • LiningToPanelOffsetX
  • LiningToPanelOffsetY
lining 2
Figure 7.1.3.1.B

The lining can only cover part of the opening reveal.

  • LiningOffset, given if lining edge has an offset to the x axis of the local placement.
lining 3
Figure 7.1.3.1.C

The lining may include a casing, which covers part of the wall faces around the opening. The casing covers the left, right and upper side of the lining on both sides of the wall. The parameters are:

  • CasingDepth
  • CasingThickness
lining 4
Figure 7.1.3.1.D

The lining may include a threshold, which covers the bottom side of the opening. The parameters are:

  • ThresholdDepth, if omitted, equal to wall thickness - this only takes effect if a value for ThresholdThickness is given. If both parameters are not given, then there is no threshold.
  • ThresholdThickness
  • ThresholdOffset (not shown in figure), given, if the threshold edge has an offset to the x axis of the local placement.
lining 5
Figure 7.1.3.1.E

The lining may have a transom which separates the door panel from a window panel. The transom, if given, is defined by:

  • TransomOffset, a parallel edge to the x axis of the local placement
  • TransomThickness

The depth of the transom is identical to the depth of the lining and not given as separate parameter.

7.1.3.1.3 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,

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.

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.

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.

IfcDoorLiningProperties (13)
5 LiningDepth OPTIONAL IfcPositiveLengthMeasure

Depth of the door lining, measured perpendicular to the plane of the door lining. If omitted (and with a given value to lining thickness) it indicates an adjustable depth (i.e. a depth that adjusts to the thickness of the wall into which the occurrence of this door style is inserted).

6 LiningThickness OPTIONAL IfcNonNegativeLengthMeasure

Thickness of the door lining as explained in the figure above. If LiningThickness value is 0. (zero) it denotes a door 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.

7 ThresholdDepth OPTIONAL IfcPositiveLengthMeasure

Depth (dimension in plane perpendicular to door leaf) of the door threshold. Only given if the door lining includes a threshold. If omitted (and with a given value to threshold thickness) it indicates an adjustable depth (i.e. a depth that adjusts to the thickness of the wall into which the occurrence of this door style is inserted).

8 ThresholdThickness OPTIONAL IfcNonNegativeLengthMeasure

Thickness of the door threshold as explained in the figure above. If ThresholdThickness value is 0. (zero) it denotes a door without a threshold (ThresholdDepth shall be set to NIL in this case). If the ThresholdThickness is NIL it denotes that the information about a threshold is not available.

9 TransomThickness OPTIONAL IfcNonNegativeLengthMeasure

Thickness (width in plane parallel to door leaf) of the transom (if provided - that is, if the TransomOffset attribute is set), which divides the door leaf from a glazing (or window) above. If the TransomThickness is set to zero (and the TransomOffset set to a positive length), then the door is divided vertically into a leaf and transom window area without a physical frame.

10 TransomOffset OPTIONAL IfcLengthMeasure

Offset of the transom (if given) which divides the door leaf from a glazing (or window) above. The offset is given from the bottom of the door opening.

11 LiningOffset OPTIONAL IfcLengthMeasure

Offset (dimension in plane perpendicular to door leaf) of the door lining. The offset is given as distance to the x axis of the local placement.

12 ThresholdOffset OPTIONAL IfcLengthMeasure

Offset (dimension in plane perpendicular to door leaf) of the door threshold. The offset is given as distance to the x axis of the local placement. Only given if the door lining includes a threshold and the parameter is known.

13 CasingThickness OPTIONAL IfcPositiveLengthMeasure

Thickness of the casing (dimension in plane of the door leaf). If given it is applied equally to all four sides of the adjacent wall.

14 CasingDepth OPTIONAL IfcPositiveLengthMeasure

Depth of the casing (dimension in plane perpendicular to door leaf). If given it is applied equally to all four sides of the adjacent wall.

15 ShapeAspectStyle OPTIONAL IfcShapeAspect

Pointer to the shape aspect, if given. The shape aspect reflects the part of the door shape, which represents the door lining.

16 LiningToPanelOffsetX OPTIONAL IfcLengthMeasure

Offset between the lining and the window panel measured along the x-axis of the local placement.

17 LiningToPanelOffsetY OPTIONAL IfcLengthMeasure

Offset between the lining and the door panel measured along the y-axis of the local placement.
