Engineering
drawing is a two dimensional representation of three dimensional objects. In
general, it provides necessary information about the shape, size, surface
quality, material, manufacturing process, etc., of the object. It is the
graphic language from which a trained person can visualize objects.
Drawings prepared
in one country may be utilized in any other country irrespective of the language
spoken. Hence, engineering drawing is called the universal language of
engineers. Any language to be communicative, should follow certain rules so
that it conveys the same meaning to everyone. Similarly, drawing practice must
follow certain rules, if it is to serve as a means of communication. For this
purpose, Bureau of Indian Standards (BIS) adapted the International Standards
on code of practice for drawing. The other foreign standards are: DIN of
Germany, BS of Britain and ANSI of America.
Role of Engineering Drawing
The ability to
read drawing is the most important requirement of all technical people in any
profession. As compared to verbal or written description, this method is brief
and clearer. Some of the applications are: building drawing for civil
engineers, machine drawing for mechanical engineers, circuit diagrams for
electrical and electronics engineers, computer graphics for one and all.
The subject in
general is designed to impart the following skills.
- Ability to read and prepare engineering drawings.
- Ability to make free - hand sketching of objects.
- Power to imagine, analyse and communicate, and
- Capacity to understand other subjects:
