|Tür - Standard|
The standard door, IfcDoorStandardCase, defines a door
with certain constraints for the provision of operation types,
opening directions, frame and lining parameters, and with certain
constraints for the geometric representation. The
IfcDoorStandardCase handles all cases of doors, that:
- are inserted into an opening, represented by
IfcOpeningElement, using the IfcRelFillsElement
- have a local placement relative to this opening, and with the
y-axis of the placement pointing into the opening direction;
- have a profile geometry, represented by
a closed curve to which the door parameters apply;
- have a reference to an IfcDoorType to define the opening
direction and the operation type (swinging, sliding, folding, etc.)
of the door. The attribute OperationType shall be provided
and not being UNDEFINED, and the attribute
ParameterTakesPrecedence shall be "TRUE";
- have an IfcDoorLiningProperties and
IfcDoorPanelProperties instances included in the set of
HasPropertySets at IfcDoorType.
HISTORY New entity in IFC4.
The geometric representation of IfcDoorStandardCase is
defined using the following multiple shape representations for its
- Profile: a three-dimensional closed curve within a
particular shape representation. The profile is used to apply the
parameter of the parametric door representation. The profile around
the edges of the opening is used to apply the door lining and door
panel shape parameter.
- MappedRepresentation: A SweptSolid, SurfaceModel, Brep
or a CSG representation additionally defining the 3D shape of the
standard door in addition to the parametric representation by
applying the IfcDoorLiningProperties and an the
IfcDoorPanelProperties to the 'Profile' representation.
Common Use Definitions
The following concepts are inherited at supertypes:
- IfcRoot: Identity, Revision Control
- IfcElement: Box Geometry, FootPrint Geometry, Body SurfaceOrSolidModel Geometry, Body SurfaceModel Geometry, Body Tessellation Geometry, Body Brep Geometry, Body AdvancedBrep Geometry, Body CSG Geometry, Mapped Geometry
- IfcBuildingElement: Product Assignment, Surface 3D Geometry
- IfcDoor: Property Sets for Objects, Quantity Sets, Material Constituents, Spatial Containment, Product Placement
The Object Typing concept applies to this entity as shown in Table 125.

Profile 3D Geometry
The Profile 3D Geometry concept applies to this entity.
The door profile is represented by a three-dimensional closed
curve within a particular shape representation. The profile is used
to apply the parameter of the parametric door representation. The
following attribute values for the IfcShapeRepresentation
holding this geometric representation shall be used:
- RepresentationIdentifier : 'Profile'
- RepresentationType : 'Curve3D' or 'GeometricCurveSet',
in case of 'GeometricCurveSet' only a single closed curve shall be
contained in the set of IfcShapeRepresentation.Items.
The following additional constraints apply to the 'Profile'
- Curve: being an IfcPolyline defining a
- Position: The curve shall lie in the xz plane of the
object placement coordinate (the y coordinate values of the
IfcCartesianPoint's shall be 0.).
EXAMPLE Figure 187 illustrates applying the door lining parameters to the
door profile shape representation. The profile defines the outer
boundary to which the door lining parameters relate as:
- IfcDoorLiningProperties.LiningDepth starting at distance
defined by LiningOffset going into the positive y
- IfcDoorLiningProperties.LiningThickness offset into the
inner side of the rectangle.
- IfcDoorLiningProperties.LiningOffset distance along the
positive y direction to where the LiningDepth applies.
- IfcDoorLiningProperties.ThresholdThickness starting at
the bottom edge of the rectangle into the inner side of the
- IfcDoorLiningProperties.ThresholdDepth starting at
distance defined by LiningOffset going into the positive y
- IfcDoorLiningProperties.TransomOffset starting at the
bottom edge of the rectangle (along local x axis) into the inner
side of the rectangle, distance provided as percentage of overall
height. Distance to the centre line of the transom.
