Current parametric design generates many possible solutions during the modelling and designing process. However, in the final stage it allows the user to choose only one solution to be developed. Physical parametric design is a design strategy for parametric design. It enables the parametric design to embody the knowledge from simulation tools and still permits a variety of possibilities at the final stage. Physical parametric design allows models varieties in a physical model, but also gives feedback to the virtual models, in order to improve the design process.
