Engineering drawing is said to be the language of an engineer, and it can be considered as a powerful tool to convey his ideas. Infact, there are evidences that pictorial language compared to other languages, dates back to very old times in its invention and usage. There are certain areas where no language other than engineering drawing can play the vital role of communication. The subject of engineering drawing, therefore, included in all engineering curricula with the aim of training the students and making them graphically literate. Attempts are made sincerely to serve this purpose by adopting a new style in the form of step-by-step construction procedures to present the subject, so that it can be easily understood. A number of chapters are designed and written with the specific purpose of training the student and helping him achieve his goal. For instance, the chapter on principles of graphics incorporating the Bureau of Indian Standards (BIS, SP: 46/1988) is aimed at training the student in standardising the pictorial language. The first chapter on draughting tools infuses in the student sufficient confidence to use modern drawing equipment. Instruction in free-hand sketching is meant to train the student in various sketching techniques, so as to convey his ideas to others effectively. The chapters on nomography, miscellaneous topics and computer graphics, as well as the contents of the other chapters are planned to serve the present need and also the possible future enrichment of the syllabi of various Universities in the country. A large number of objective questions covering all chapters are also included at the end of each chapter. These questions help the student in self-study, and the teacher in assessing the student’s ability.
