Abstract

With non-availability of the required equipment, teaching engineering drawing to a class of over 1000 students and retaining their interests and attention from the beginning to the end of a lecture period was of big concern to the engineering drawing courses lecturers in the Faculty of Engineering, Nnamdi Azikiwe University, Awka. This work is aimed at designing and developing animated Microsoft Office PowerPoint teaching applications named 2-D Computer-Aided Drafting Applications (2-D CADA) that eliminate this problem. This paper presents a sample of the Applications which demonstrates clearly to the audience’s pleasure how to mount, set and hold a drawing sheet on a drawing board before actual drawing commences. It also shows how to manually draw boarder lines on the drawing sheet. Similar programs can be written and used to show to engineering students how to manually draw most of the figures specified in their schools' curricula using engineering drawing instruments. Many of this Application have been written on various topics in engineering drawing in line with the global trend of drudgery reduction in man-machine systems. These Applications are already being deployed in teaching engineering drawing in the Faculty of Engineering, Nnamdi Azikiwe University, Awka, Nigeria. The benefits of employing 2-D CADA in teaching and learning engineering drawing are overwhelming. 2D-CADA relieves a teacher the mental and physical stresses that go with manual production of drawings on a chalk board. It drastically improved the attention, interest and understanding of students during drawing lessons. A well written 2D-CADA can be replicated and deployed to a personal computer for self-study plans as well as to group-based students’ workstations for group teaching.
