Computer Graphics Production of Switchgear Engineering Drawings

The opportunities for applying coomputer graphics and com puter-aided design (CAD/CAM) to switchgear engineering drawings are examined in a case study of one switchgear manufacturer´s computer system. This system is of unusual interest because it is particularly strong in two features which are seldom achieved: 1) flexibility in drawing layout and content, and 2) greater computer assistance in most steps in producing engineering drawings. An explanation of the choices, and capabilities in computer- aided design systems for switchgear is presented. In addition, guidelines in designing or choosing a system that allows flexibility and maximum computer assistance in producing the drawings are noted.
