Today, we will discuss What is the concept of BIM? What does BIM mean? In recent years, with the advancement of information technology, the Building Information Modeling (BIM) approach has gained significant attention in the Architecture, Engineering, and Construction (A/E/C) industry. BIM uses a standardized data format for exchanging graphic files, enabling the integration of both graphical and non-graphical information into a single model. This integration reduces unnecessary data format conversions and reliance on paper documents, enhances consistency and efficiency in information processing, and facilitates information exchange and sharing throughout the various stages of a project’s lifecycle.
BIM (Building Information Modeling) refers to the creation and use of “computable digital information” during the design and construction phases of a building. This digital information can be automatically managed by software systems, ensuring that all related documents and data remain consistent and synchronized. Unlike traditional CAD, which mainly handles vector data, BIM is based on a parameterized model. In the BIM database, every object is defined with parameters, allowing users to select only the necessary objects from the database to build the BIM model when creating building engineering drawings.
BIM essentially employs the concept of Object CAD. In CAD terminology, an object is a distinct entity, and Object CAD refers to object-oriented CAD systems. Object-oriented means that the design tools focus on objects rather than disconnected elements like points, lines, or circles. For example, when a user draws a window in a BIM-enabled CAD interface, they use the “window” command and position it on a wall. The wall then automatically creates an opening at the window’s location, and the window becomes linked to the wall. Additionally, when selecting the window’s properties, users can see details such as its name and type, rather than just generic 2D shapes as in traditional AutoCAD interfaces.
The BIM database can be considered a 3D model. In a BIM system, 2D drawings are projections of this 3D model onto various planes. This means that by constructing a 3D building model within a BIM system, all necessary drawings—such as floor plans, elevations, sections, and perspective views (including line drawings, colored views, and rendered images)—can be generated directly. This approach significantly saves the time traditionally required to repeatedly draw these views in AutoCAD, allowing designers to focus more on meaningful aspects of building design.
