Abstract: In the design process of prefabricated building prefabricated components, although the prefabricated components are similar in form, the specific size and specifications are quite different, which often leads to a high error rate in the design process and reduces the overall design efficiency. Based on the development status of BIM technology in the field of prefabricated structural design, this paper takes a new prefabricated steel-concrete composite shear wall structure prefabricated component as the research object, uses C# programming language, conducts a secondary develop of Revit software, combines the operation essence of data-based parameterization, supplements the functional limitations of the software, and automatically controls and adjusts the creation and modification of the model by constructing a visual parameter adjustment interface. The software design is concise and clear, and the function settings are rich and practical, which greatly improves the three-dimensional design efficiency of the structure, and provides research ideas and references for the design of different types of new process combination structures.
