Abstract: To reduce cognitive burden of designers and improve efficiency of integrated modeling, a Computer Aided Design/Computer Aided Engineering (CAD/CAE) integrated modeling method was proposed. With definition of characteristics domain, natural classification for domain knowledge of integrated model was achieved. Structure component was constructed as characteristics carrier, and the domain knowledge was applied in characteristic solution. A sequential modeling process was established by integrating internal restriction and external association of the structure components. Based on characteristic incidence matrix, dynamic management of characteristics association was realized. Furthermore, characteristic linkage of model modification was fulfilled and a product CAD/CAE integrated model was constructed. An analysis system of building steel structure based on the proposed method was developed to verify the correctness and effectiveness in a grid design.
