Abstract
The design or form styling process of industrial products begins with sketching by the designer, after which the designer embodies the required form using character lines. Character lines serve as important parameters for depicting the design of a form in the aesthetic design of industrial products. The objective of this study was to develop a CAD system which can create these character lines on a surface model. The operations of the system must be very simple; entering the character lines equivalent to the sketch drawn, and entering the type and parameters of these lines. In this study, the algorism of this system was proposed and its uses confirmed by constructing the basic system.
