In recent years, Building Information Modeling (BIM) technology has been widely used in the field of architectural engineering, bringing new changes to structural design methods. However, the promotion of BIM forward design for structural specialties in China has encountered significant obstacles. Currently, structural BIM forward design often struggles with linear expression and flat method annotation as per Chinese standards, making it difficult to meet the current two-dimensional (2D) drawing delivery requirements in China. Designers need to expend considerable effort to refine drawing details, leading to a substantial repetitive workload. Therefore, based on the frontline work of designers, deeply analyzes the pain points and underlying causes of current BIM structural construction drawing design and proposes a two- and three-dimensional (2D-3D) integrated BIM structural design method. The core technology of this method revolves around two- and three-dimensional hybrid cutting technology, dynamic association technology for design information, quick design and automatic generation technology for construction drawings, and intelligent checking technology. Finally, the domestic software CSWADI EasyBIM, developed by China Southwest Architectural Design and Research Institute Corp. Ltd, is utilized to implement this method and conduct comprehensive applications in actual projects. The results indicate that this method is compatible with both 2D design habits and 3D information model expression, significantly enhancing the efficiency and quality of structural BIM forward design.
