GlobalID | I | IfcGloballyUniqueId : Assignment of a globally unique identifier within the entire software world. | Text |
Name | N | Name of Product | Text |
Description | D | IFC Description | Text |
ObjectType | T | The type denotes a particular type that indicates the object further. The use has to be established at the level of instantiable subtypes. In particular it holds the user defined type, if the enumeration of the attribute PredefinedType is set to USERDEFINED. | Text |
ObjectPlacement | P | IfcObjectPlacement : Placement of the product in space, the placement can either be absolute (relative to the world coordinate system), relative (relative to the object placement of another product), or constraint (e.g. relative to grid axes). It is determined by the various subtypes of IfcObjectPlacement, which includes the axis placement information to determine the transformation for the object coordinate system. | Generic Data |
Representation | R | Reference to the representations of the product, being either a representation (IfcProductRepresentation) or as a special case a shape representations (IfcProductDefinitionShape). The product definition shape provides for multiple geometric representations of the shape property of the object within the same object coordinate system, defined by the object placement. | Geometry |
Tag | T | The tag (or label) identifier at the particular instance of a product, e.g. the serial number, or the position number. It is the identifier at the occurrence level. | Text |
Material | M | IfcMaterial from element or relating type | Generic Data |
FillsVoids | F | IfcOpeningElement: Opening Element being filled | Generic Data |
ConnectedTo | C | Reference to the element connection relationship. The relationship then refers to the other element to which this element is connected to. | Generic Data |
IsInterfereredByElements | I | Reference to the interference relationship to indicate the element that is interfered. The relationship, if provided, indicates that this element has an interference with one or many other elements. | Generic Data |
InterferesElements | I | Reference to the interference relationship to indicate the element that interferes. The relationship, if provided, indicates that this element has an interference with one or many other elements. | Generic Data |
HasProjections | P | Projection relationship that adds a feature (using a Boolean union) to the IfcBuildingElement. | Generic Data |
ReferencedInStructures | R | Reference relationship to the spatial structure element, to which the element is additionally associated. This relationship may not be hierarchical, an element may be referenced by zero, one or many spatial structure elements. | Generic Data |
HasOpenings | O | Reference to the _IfcRelVoidsElement_ relationship that creates an opening in an element. An element can incorporate zero-to-many openings. For each opening, that voids the element, a new relationship IfcRelVoidsElement is generated. | Generic Data |
IsConnectionRealization | C | Reference to the connection relationship with realizing element. The relationship, if provided, assigns this element as the realizing element to the connection, which provides the physical manifestation of the connection relationship. | Generic Data |
ProvidesBoundaries | B | Reference to space boundaries by virtue of the objectified relationship IfcRelSpaceBoundary. It defines the concept of an element bounding spaces. | Generic Data |
ConnectedFrom | C | Reference to the element connection relationship. The relationship then refers to the other element that is connected to this element. | Generic Data |
ContainedIn | S | Containment relationship to the spatial structure element, to which the element is primarily associated. This containment relationship has to be hierachical, i.e. an element may only be assigned directly to zero or one spatial structure. | Generic Data |
HasCoverings | C | It defines the concept of an element having coverings associated. | Generic Data |
