BIM is a building information model and a new tool for architecture, engineering and civil engineering. The term "building information model" or "building information model" was created by Autodesk. It is used to describe those computer-aided designs that are mainly three-dimensional graphics, object-oriented and related to architecture.

The core of BIM is to establish a virtual three-dimensional model of construction engineering by using digital technology, and provide a complete and consistent information base of construction engineering for this model.

Extended data

BIM has the following four characteristics:

1, visualization

Visualization is a form of "what you see is what you get". For the construction industry, the real application of visualization in construction industry is very important.

2. Coordination

Coordination is the key content in the construction industry, and the construction unit, the owner and the design unit are all doing coordination and cooperation.

Step 3 simulate

Simulation can not only simulate the designed building model, but also simulate things that cannot be operated in the real world.

4. Optimality

In fact, the whole process of design, construction and operation is a process of continuous optimization.
