Abstract : 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.Irrespective of language barriers, the drawings can be effectively used in other countries,
in addition to the country where they are prepared. Thus, the engineering drawing is the universal language of all engineers.
Engineering drawing has its origin sometime in 500 BC in the regime of King Pharos of egypt when symbols were used to convey the ideas among people.
