Application and Expression of Nonlinear Architectural Design Based on BIM Platform

The development of science and technology and social economy has made the continuous improvement of architectural technology, some representative design methods and technologies have also been derived in the architectural design method, BIM is a new type of design technology means, information data is used as the model basis, thus conducting modeling and information expression. This paper utilizes the BIM platform to design the nonlinear building "mountains and rivers qintai", the application of BIM technology on information interoperability and information expression of nonlinear architectural design is explored, combined with the advantages of BIM, the scheme is deepened through data and information control, analysis and simulation and so on, thus exploring the information expression and transmission of the 3D visualization of nonlinear architectural design information under the BIM platform, and an ideal physical building model is established.
