Traditional design methods have problems such as low efficiency of multidisciplinary collaboration. We built a multidisciplinary collaboration database based on the BIM platform, integrated multi-source professional data using the IFC standard, and developed an automatic collision detection plug-in using the Revit API. We used GA and PSO algorithms to drive the generation of architectural forms, and performed multi-objective optimization calculations on the Rhino.Compute cloud cluster. We further used GCN to extract features from historical project data, train GAN, and output innovative solutions that meet regulatory constraints. The new design concept shortened the design time; in terms of innovation scores, the new design concept scored the highest 5.0 in all tasks.
