The advances of generative and parametric CAD tools have enabled designers to create designs representations that are responsive, adoptable and flexible. However, the complexity of the models and limitation of human-visual systems posed challenges in effectively utilizing them for sensitivity analysis. In this prototyping study, we propose a method that aims at reduction of these challenges. The method proposes to improve visually analysing sensitivity of a design model to changes. It adapts Model-View-Controller approach in software design to decouple control and visualization features from the design model while providing interfaces between them through parametric associations. The case studies is presented to demonstrate applicability and limitation of the method.
