Entity-based modelling and Object-based modelling have been two distinct lines of products since the introduction of Computer-Aided Design (CAD) in the marketplace some twenty years ago. Although majority of practitioners have opted for entity-based modelling, the enhancement of object-based modelling has continued. In line with the increasing computer hardware and software capability, most CAD vendors have launched more powerful object-based CAD software in recent years. These software are now commonly known as Building Information Modeling (BIM), Virtual Building, Parametric Modeling or Model-Based Design. The move is considered to be revolutionary in the world of the construction CAD market, and would enable seamless downstream applications of the rich model information. Based on hand-on testing, this paper examines the provision of the data interfaces and the modelng objects in two BIM software. It is recommended that more user-friendly interfaces for embedding extra parameters into the modelling objects should be provided. BIM vendors should also support third-party development by enabling the application programming interfaces and data exchange standards such as IFC and XML.
