Part of a series designed for students at schools and craft colleges in developing countries, this book covers subjects such as drawing office practice, orthographic projection, sectional views, screw threads, engineering fasteners, assembly drawing, pictorial drawing, design processes and materials. It is one of three books which aim to provide comprehensive coverage of all aspects of secondary school technical drawing syllabuses. They are also suitable for craft level courses such as engineering and building- related subjects and for industrial learning courses where an understanding of technical drawing is required. The text contains self-study exercises and should be appropriate for a wide range of industrial and vocational courses, and for preparing students to take City and Guilds of London Institute examinations or a local equivalent.
