Abstract
Many products having free form of sculptured surfaces are designed by traditional methods by crafting prototypes. This requires skill. Analysis of these products often reveals that they have an established general form and are designed around a number of dominant features. A feature-based design system is proposed based on extended surfaces and blends that provides designers with considerable flexibility for feature replacement and manipulation. The implications of this approach on the rapid production of prototypes for both design appreciation and manufacturability is discussed. A range of golf clubs has been used as the example around which the methodology has been developed.
