The concept of BIM is to collect knowledge, create and integrate a virtual three-dimensional space model, build a three-dimensional virtual building by computer, accurately visualize the concept of designers, and provide complete plans, elevations and sections. In addition, it is necessary to list the schedule, manage it synchronously with the design drawings, and change it immediately. This can solve the problem that the solution is based on the relationship between the model and the drawings at the same time, because its project document is a by-product of the 3D model.
Therefore, BIM is a technology and an idea. The main operating software includes Autodesk's Reivt series, ArchiCAD for soft graphics, Microstation for Bentley and Tekla for Tianbao. Its main function is to integrate design information and building attribute data information.
