Technical Drawing 1: Plane and Solid Geometry is the first of three books which together provide comprehensive coverage of all aspects of secondary school technical drawing syllabuses. The books are also suitable for Craft level courses such as engineering and building related subjects and for industrial training courses where an understanding of technical drawing is required. The three books may be used together or seperately to suit a variety of needs. Using numerous illustrations and easy-to-follow text, this book covers: basic drawing equipment; drawing polygons; circles and other loci; enlargement and reduction; isometric; orthographic; oblique and auxiliary projection; freehand sketching; sections; true shapes and lengths; interpenetrations; developments; the helix. Other features of this book include exercises which may be used for self-study, revision or evaluation, and a useful glossary of key terms.
