Most of the orthographic views are accompanied by the pictorial views of the objects to enable the students to visualize the shapes easily. The chapter on Engine Parts are given in two separate chapters such as (1) Steam Engine Parts and (2) Internal Combustion (I.C.) Engine Parts. This edition is consist of: * 977?Self explanatory and neatly drawn sketches * ?57?Useful tables * 410?Exercises at the end of chapters A chapter to learn Computer Aided Drafting (CADr) is entirely rewritten with 52 self-interactive and self-learning practice modules. The book covers the syllabi of Machine Drawing to meet the requirements of students of Mechanical Engineering Degree Examinations of all the Indian Universities as well as Diploma Examinations conducted by various Boards of Technical Education, Certificate Courses as well as for I.T.I. students and also to the candidates reading for the A.M.I.E., U.P.S.C., G.A.T.E. and similar competitive and professional examinations.
