Building Information Modeling (BIM) has become a concept for all who are involved in design within the construction industry. It became the equal sign between 3D models and BIM, but the development shows that the fact is not so. The Term “Modelling” is a generic term for the Abstract information about the total Digital model of the building or construction. Both 2D and 3D models are components within the Digital abstract model called BIM. We can add more dimensions such as time and cost what science has declared as 4D and 5D. There are other aspects of the model such as warranty, control systems controlling the indoor climate, all are a part of the total Model.
