Abstract: The lack of a unified format for data exchange among BIM software and the low efficiency in information exchange lead to the extension of the project duration and the increased cost in the power generation industry. By comparing the existing foreign standards such as IFC, STEP, OBJ, and the PModel data exchange file format implemented by domestic BIM software BIMBase, this paper studies the process of parsing, reading, importing, and modeling, as well as optimizing data delivery method, thereby provides a practical method to solve the problem of BIM software data exchange in the power generation industry.
