This paper explains the approach employed by GM Styling Staff personnel in developing automobile windshields from the daylight opening line with computer graphics. The manual method for developing windshields is examined first. This is followed by a brief resume of the major software and hardware components used by the windshield program in the DAC-I (Design Augmented by Computers) System. The general procedure for producing an automobile windshield with computer graphics is then presented. Conclusions based on the use and potential of computer graphics in a production environment and the ability of designers to relate to the graphic console terminates the report.
