Machine Drawing and Drafting - A technical person can use the graphic language as powerful means of communication with
others for conveying ideas on technical matters. However, for effective exchange of ideas with
others, the engineer must have proficiency in (i) language, both written and oral, (ii) symbols
associated with basic sciences and (iii) the graphic language. Engineering drawing is a suitable
graphic language from which any trained person can visualise the required object. As an
engineering drawing displays the exact picture of an object, it obviously conveys the same
ideas to every trained eye.
