Engineering Drawing is one of the most essential foundations on which the industrial sector initiates the research and development, design, manufacturing, quality control and distribution of its products. Thanks to the rapid advances in the development of computer software and hardware, the representation of engineering drawing has progressed from traditional manual and instrumental drawing to computer aided drawing (CAD), which has become increasingly prevalent as one of the fundamental abilities in engineering drawing. As the industrial sector is working toward overall automation, a wide variety of computer equipment and innovative professional drawing software packages are applied in the process in order to achieve more accurate and efficient drawing.
CAD uses computer to assist engineering drafting. As mechanical drawing is an integral part of engineering drawing, the study, based on the general applications of CAD in mechanical industry, aims to construct a competency inventory in computer aided mechanical drawing (CAMD) so as to build a profile of technical talent needed by the industrial sector.
In this paper we developed a competency inventory for CAMD technicians in the mechanical sector by conducting interviews, questionnaire surveys, and panel discussions. It is then concluded that CAMD involves three tasks: general drawing, professional drawing, and computer operation. The task of general drawing may be further divided into parts drawing, assembly drawing, and exploded pictorial drawing. In addition, there are a total of 15 competencies required in CAMD technicians; nine for general drawing, four for professional drawing and two for computer operation. The analysis based on the cognitive theory concluded that a total of 81 knowledge items are involved in CAMD; 47 for general drawing, 16 for professional drawing, and 18 for computer operation.
