[email protected] ABSTRACT The advancement of computers in both hardware and software has led to the replacement of hand-held instruments with CAD system in engineering graphics course. The syllabus of engineering graphics courses has also shifted more towards learning the CAD system. This paper provides an in-depth examination of engineering graphic course content and proposed a well-balanced course content between fundamentals of graphics and CAD. It also includes a brief overview of scheduling and course evaluation methodology. Keywords engineering graphics, CAD, facilitating learning, course content INTRODUCTION A change in the drawing tools, from on learning the CAD software rather hand-held instruments to computers, than graphics fundamentals. The Graphics has been heralded as one of has inadvertently led to a shift in challenge to facilitate engineering the cornerstone in engineering, as an course objective and students interest graphics is further compounded by effective medium of communication [1]. The syllabuses of engineering the difficulty in scheduling an effective between engineers and other technical graphics courses have slightly diverted program. persons in engineering profession. from its main objective of teaching Almost all engineering schools related students so that they can read and The course content should be well in mechanical or chemical engineering write the graphic language clearly balanced between fundamentals of discipline provide for a course in using universally accepted symbols, graphics and computer-aided design. Engineering Graphics. This course conventions, standards and principles. In the development of an engineering used to be conducted in a classroom Lately, it was found that more often graphics course, it is necessary to or laboratory equipped with drawing the course content for engineering consider this new engineering boards, T-square, set-squares and graphics courses tend to focus more environment and formulate course other hand-held instruments. The on the need to learn the ropes of the objectives which will ensure that advancement of computers, hardware software. Facilitators and future engineers will be best prepared and software, has led to the demonstrators also tend to dwell on to efficiently use CAD tools to replacement of hand-held instruments the CAD software instead of focusing communicate their ideas and design with computer-aided design, CAD, as on the fundamentals of graphic solution [2]. a tool for facilitating learning. language.
