Design ideas are examined and then narrowed down. A few design directions are selected, and in each direction, design ideas are refined in terms of aesthetic, functions as well as other implications defined in the conceptualization stage. This process involves scale models and CAD modeling when appropriate.
Examples from Master's Degree Project
CAD modeling plays an important role for refining details as well as for comparing appearance of different design directions.
CAD Modeling
Design issues are clarified in the design development stage. In the design refinement stage, those technical issues are further examined with CAD models. CAD is a powerful tool to study geometry of industrial products.
The joinery designs, considered through hand drawings in the previous stage, are then examined with CAD drawings.
CAD rendering is also a powerful tool to consider the appearance of the model. It can tremendously reduce time and effort to compare similar but different design directions.

CAD Modeling
This model is, as described later in Design Finalization and Presentation, designed to be assembled out of off-the-shelf materials with school facilities.
Examples from Studio Projects
CAD modeling, Toothbrush -nature-
When I made a sketch model with rigid foam and plasticine, people could image many things from it. However, colouring would limit people's perception. I use CAD drawing to explore possible colour coordinates so that it would leave room for imagination.
