We compared the methods of modelers who modeled in clay and those who modeled in CAD. We gave special attention to the size and shape characteristics of the model, and to the differences in approach between individual modelers. Four modelers made three different objects in clay and four other modelers made the same three objects in CAD. As a measure of success of the modeling method, we used the quality of the generated model, based on a set of criteria. Generally, the overall appearance of the clay models was better than that of the CAD models. Individual modelers applied different approaches for the same shape, not only when using clay, but also during CAD modeling. The quality of the models varied greatly. We conclude that the most appropriate modeling method depends on the size and shape character of the model, and also of the preferences and skills of the subjects.
