Abstract

This paper focuses on the application of BIM technology in the construction of 3D digital city. Digital architecture, as the basic unit of digital city, is an important part of the process of urban informatization. With the development of science and technology, people have put forward higher requirements for the three-dimensional model of digital city. This paper first introduces the current digital urban engineering, and the hot spot in the construction of digital city (3DCM). Then it lists the traditional modeling method of 3D city model, and points out that the traditional modeling method has a large amount of modeling engineering, and the quality of the model is not enough.BIM, as the beginning of digital city, brings vitality to digital cities. Based on the deficiencies in the current digital city construction, this paper expounds the two ways of combining BIM with digital city, and probes into the BIM in architectural planning. Then it introduces the revolutionary technology of the engineering field information - BIM, and demonstrates the feasibility of applying the BIM technology to the 3D city model with the technical features of the BIM.
