The door is a built element that is predominately used to provide controlled access for people, goods, animals and vehicles. It includes constructions with hinged, pivoted, sliding, and additionally revolving and folding operations. A door can:be a "free standing" door, contained in an IfcSpatialElement such as an IfcBuildingStorey. fill an opening, typically in a wall. The door will then have a FillsVoids attribute which uses the IfcRelFillsElement relationship to relate the IfcDoor with the IfcOpeningElement; be part of an element assembly, typically an IfcCurtainWall. The door will then have a Decomposes attribute which uses the the IfcRelAggregates relationship to relate the door with the assembly of elements;There are two main representations for door occurrences:IfcDoor entities that have a 3D rectangle 'Profile' shape representation defined. This profile can then be used to parametrically generate the geometry of a door. If not provided, the profile of the IfcOpeningElement can be used if the door fills an opening. The parameters are specified on the relating IfcDoorType that references IfcDoorLiningProperties and IfcDoorPanelProperties for each panel in the door; IfcDoor entities that are not parametrically generated and have only 'Brep', or 'SurfaceModel' geometry.In addition, an IfcDoor may commonly include a 'FootPrint' representation defining the 2D shape of the door and its swing.The parameters of a door are defined by both the IfcDoor occurence and its IfcDoorType. The IfcDoor specifies:the door width and height the door opening direction (by the positive y-axis of the ObjectPlacement)The IfcDoorType specifies parameters which are common to all of its occurrences of IfcDoor: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 particular attributes for the lining by the IfcDoorLiningProperties the particular attributes for the panels by the IfcDoorPanelPropertiesREFERENCE Definition according to ISO 6707-1: construction for closing an opening, intended primarily for access with hinged, pivoted or sliding operation. NOTE The entity IfcDoorStandardCase has been deleted. Use an IfcDoor with a 'Profile' representation instead. The IfcDoor should also have an IfcDoorType with ParameterTakesPrecedence set to 'TRUE'.

A ramp is a vertical passageway which provides a human or vehicle circulation link between one floor level and another floor level at a different elevation. It may include a landing as an intermediate floor slab. A ramp normally does not include steps.{ .extDef}NOTE Definition according to ISO 6707-1: Inclined way or floor joining two surfaces at different levels.The IfcRamp shall either be represented:as a ramp assembly that aggregates all parts(ramp flight, landing, etc.) with own shape representations, or as a single ramp without decomposition including all shape representations directly at the ramp entity.NOTE In case of an IfcRamp being the assembly of all parts of the ramp the aggregation is handled by the IfcRelAggregates relationship, relating an IfcRamp with the related IfcRampFlight and landings, IfcSlab with PredefinedType=LANDING. IfcRailing's belonging to the ramp may also be included into the aggregation. NOTE Model View Definitions and implementer agreements may restrict the IfcRamp being an assembly to not have an independent shape representation, but to always require that the decomposed parts have a shape representation. In this case, at least the 'Body' geometric representations shall not be provided directly at IfcRamp if it is an assembly. The 'Body' geometric representation of the IfcRamp is then the sum of the 'Body' shape representation of the parts within the decomposition structure. HISTORY New entity in IFC2.0.
A spatial element is the generalization of all spatial elements that might be used to define a spatial structure or to define spatial zones.a hierarchical spatial structure element as IfcSpatialStructureElement a spatial structure is a hiearchical decomposition of the project. That spatial structure is often used to provide a project structure to organize a building project. A spatial project structure might define as many levels of decomposition as necessary for the building project. Elements within the spatial project structure are site, building, storey, and space or alternatively, site, bridge and bridge part a spatial zone as IfcSpatialZone a spatial zone is a non-hierarchical and potentially overlapping decomposition of the project under some functional consideration. a spatial zone might be used to represent a thermal zone, a lighting zone, a usable area zone. a spatial zone might be used to represent a horizontal spatial structure as used in civil works. a spatial zone might have its independent placement and shape representation.HISTORY New entity in IFC4.
A stair is a vertical passageway allowing occupants to walk (step) from one floor level to another floor level at a different elevation. It may include a landing as an intermediate floor slab.{ .extDef}NOTE Definition according to ISO 6707-1: Construction comprising a succession of horizontal stages (steps or landings) that make it possible to pass on foot to other levels.The IfcStair shall either be represented:as a stair assembly entity that aggregates all parts (stair flight, landing, etc. with own representations), or as a single stair entity without decomposition including all representation directly at the stair entity.NOTE In case of an IfcStair being the aggregate of all parts of the stair the aggregation is handled by the IfcRelAggregates relationship, relating an IfcStair with the related IfcStairFlight and landings, IfcSlab with PredefinedType=LANDING. IfcRailing's belonging to the stair may also be included into the aggregation. NOTE Model View Definitions and implementer agreements may restrict the IfcStair being an assembly to not have an independent shape representation, but to always require that the decomposed parts have a shape representation. In this case, at least the 'Body' geometric representations shall not be provided directly at IfcStair if it is an assembly. The 'Body' geometric representation of the IfcStair is then the sum of the 'Body' shape representation of the parts within the decomposition structure. HISTORY New entity in IFC2.0.
A zone is a group of spaces, partial spaces or other zones. These spaces may or may not be adjacent. A zone does not have its own shape representation. Zone structures may not be hierarchical (in contrary to the spatial structure of a project - see IfcSpatialStructureElement), i.e. one individual IfcSpace may be associated with zero, one, or several IfcZone's. IfcSpace's are grouped into an IfcZone by using the objectified relationship IfcRelAssignsToGroup as specified at the supertype IfcGroup. For example, a zone might be used to represent an apartment as a group of spaces.NOTE Certain use cases may restrict the freedom of non hierarchical relationships. In some building service use cases the zone denotes a view based delimited volume for the purpose of analysis and calculation. This type of zone cannot overlap with respect to that analysis, but may overlap otherwise. HISTORY New entity in IFC1.0
