Engineering Graphics with an Introduction to AutoCAD

Book excerpt: Although the world of drawing has changed from graphite technology (i.e. conventional pencils, drawing paper, instruments and associated skills) to graphic technology (i.e. computer assisted drawing and drafting), the basics of the subject are equally important in either of the approaches. The teaching-learning process for engineering drawing calls for more imaginative thinking on the part of the student than may be needed for learning other subjects and ingenious ways for the teacher for communicating with the students so as to develop a scheme that enables a student to translate 3D visualization into a 2D graphic representation on a drawing in an easy manner. Learning engineering drawing is thus learning a new language for effective communication and uniform understanding between people dealing with physical objects. The book also includes a chapter on AutoCAD which will serve as a good course material to students and teachers of engineering drawing. The language used for presentation has been simple, since the focus is the first year students just entering the engineering discipline. The CD enclosed with the book contains “Power point presentations on Conversion of Orthographic view to Isometric and Conversion of Pictorial view to Orthographic Projections” to facilitate students as well as the teachers.
