The present invention relates to the technical field of urban rail transit design. Disclosed are an intelligent method and system for importing a BIM model into a rendering engine in urban rail transit engineering. When importing a BIM model into a rendering engine, due to different modeling software and different coordinate systems, the correctness of BIM model import cannot be guaranteed, and manual review of the result is needed after the model is imported, resulting in low efficiency and a high error rate. Moreover, existing transformation methods do not have universal applicability. In the present invention, coordinate information of components in a BIM model is automatically extracted, reference coordinate information of the components in a BIM coordinate system is calculated, and then reference coordinate information of the BIM model in a rendering engine coordinate system is obtained by means of transformation between coordinate systems, to complete transformation. According to the present invention,
