This paper presents an interactive framework that balances visual exploration of
design variations with their structural implications, in the case of the design of truss structures with aesthetic criteria. Based on the assumption that aesthetic design goals are not easily quantifiable, key elements for an interactive optimization framework are derived and implemented. Starting with an initial design, the user can visually assess interesting solutions, save them for later assessment, actively drive the optimization towards individual goals, reinitialize
the optimization with a set of available solutions, or restart the design process. In addition, a criterion is introduced to measure the similarity of the shape of candidate solutions with respect to reference designs. The framework is then applied in the design of a truss tower. The effectiveness of the similarity criteria, as well as the ability of the user to drive the optimization towards specific design goals is demonstrated. The result is a framework that is conducive to the visual exploration of architectural variation coupled with structural constraints.
