Knowledge acquisition for developing design knowledge bases is difficult and time consuming. In this paper, a new approach for acquiring design knowledge is presented. The object‐oriented approach is applied to model the design objects and the design process. It is discussed that in the case of routine bridge design, synthesis of the bridge structure can be achieved through recursive top‐down refinement using selection among predefined types, and decomposition of the structure into predefined components. Having this design model, a methodology for using analogy to augment the knowledge base is proposed. Analogy can be used to retrieve and modib an available design object in order to create a similar object interactively. A prototype system that implements this methodology is presented.
