Explaining all the concepts of machine drawing through illustrations and minimum theory, the book tries to give a near visual appeal to the book. The books assumes no prior knowledge of the subject and hence starts from the fundamental topics such as simple geometric constructions, orthographic and isometric projections, and moves on to the drawing of different machine elements, assembly drawing of machine parts, limits, tolerance, and fits, and surface roughness and finish. A chapter on
AutoCAD commands and computer graphics has been included in the beginning of the book and in the later chapters along with hand drawings, drawings using the AutoCAD software are also explained.
Packed with numerous end chapter exercises in the form of multiple choice questions, review questions, drawing exercises, and CAD exercises, the book provides ample practice to ensure students apply each and every concept learnt through the book.
