Figure 5.3: Elevator Car Class and its Attributes in the IFC System
• Attributes (or Parameters) are information about the class or its
interface and are added to fully define an AEC object. Length, width,
height, and location are some typical attributes of AEC objects.
Figure 5.4: An IFC Relationship Diagram of Elevator Car and its Frame
• Relationships occur between classes. For example, an elevator car
has a relationship to its structural frame. A structural frame contains
a car and reciprocally a car is contained by a structural frame
(Figure 5.4).
• Interfaces are used to provide access to the object. IFC interfaces
are designed to support the AEC processes, and enable software
vendors to implement IFC based objects. For example, an elevator
