##### Semantic definitions at the entity

Entity definition

The door is a building element that is predominately used to provide controlled access for people and goods. It includes constructions with hinged, pivoted, sliding, and additionally revolving and folding operations. A door consists of a lining and one or several panels.

> NOTE Definition according to ISO 6707-1: construction for closing an opening, intended primarily for access with hinged, pivoted or sliding operation.

The IfcDoor defines a particular occurrence of a door inserted in the spatial context of a project. A door can:

- be inserted as a filler in an opening using the IfcRelFillsElement relationship, then the IfcDoor has an inverse attribute FillsVoids provided;

  > NOTE View definitions or implementer agreements may restrict the relationship to only include one door into one opening

- be part of an element assembly, in general an IfcCurtainWall, using the IfcRelAggregates relationship, then the IfcDoor has an inverse attribute Decomposes is provided;
- be a "free standing" door, then the IfcDoor has no inverse attributes FillsVoids or Decomposes provided.

This specification provides two entities for door occurrences:

- IfcDoorStandardCase used for all occurrences of doors, that have a 'Profile' shape representation defined to which a set of shape parameters for lining and framing properties apply. Additionally it requires the provision of an IfcDoorType that references one IfcDoorLiningProperties and on to many IfcDoorPanelProperties;

  > NOTE see IfcDoorStandardCase for all specific constraints imposed by this subtype.

- IfcDoor used for all other occurrences of doors, particularly for doors having only 'Brep', or 'SurfaceModel' geometry without applying shape parameters.

The actual parameters of the door and/or its shape are defined by the IfcDoor as the occurrence definition (or project instance), or by the IfcDoorType as the specific definition (or project type). The following parameters are given:

- at the IfcDoor or IfcDoorStandardCase for occurrence specific parameters. The IfcDoor specifies:
- - the door width and height
  - the door opening direction (by the y-axis of the ObjectPlacement)
- at the IfcDoorType, to which the IfcDoor is related by the inverse relationship IsTypedBy pointing to IfcRelDefinesByType, for type parameters common to all occurrences of the same type.
- - the operation type (single swing, double swing, revolving, etc.)
  - the door hinge side (by using two different styles for right and left opening doors)
  - the construction material type
  - the particular attributes for the lining by the IfcDoorLiningProperties
  - the particular attributes for the panels by the IfcDoorPanelProperties

> HISTORY New entity in IFC1.0.

> IFC4 CHANGE The attributes PredefinedType and OperationType are added, the applicable type object has been changed to IfcDoorType.

The geometric representation of IfcDoor is given by the IfcProductDefinitionShape, allowing multiple geometric representations. The IfcDoor may get its parameter and shape from the IfcDoorType. If an IfcRepresentationMap (a block definition) is defined for the IfcDoorType, then the IfcDoor inserts it through the IfcMappedItem.

The geometric representation of IfcDoor is defined using the following (potentially multiple) IfcShapeRepresentation's for its IfcProductDefinitionShape:

- Profile: A 'Curve3D' consisting of a single losed curve defining the outer boundary of the door (lining). The door parametric representation uses this profile in order to apply the door lining and panel parameter. If not provided, the profile of the IfcOpeningElement is taken.
- FootPrint: A 'GeometricCurveSet', or 'Annotation2D' representation defining the 2D shape of the door
- Body: A 'SweptSolid', 'SurfaceModel', or 'Brep' representation defining the 3D shape of the door.

In addition the parametric representation of a (limited) door shape is available by applying the parameters from IfcDoorType referencing IfcDoorLiningProperties and IfcDoorPanelProperties. The purpose of the parameter is described at those entities and below (door opening operation by door type).

The overall size of the IfcDoor to be used to apply the lining or panel parameter provided by the IfcDoorType is determined by the IfcShapeRepresentation with the RepresentationIdentifier = 'Profile'.
