 Engineering Drawing/graphic tools

Drawing is the language of engineers. Thousands (1000) of words cannot describe a part correctly which a single drawing represents accurately. Ideas of engineers are recorded by preparing a drawing, and execution of work is also carried out on basics of drawings. Communication of engineers is done with the help of drawings. Like music, drawing is an universal language of the engineering world.

Drawing instruments are used to prepare drawings easily and accurately. The accuracy of drawings depends on the quality of instruments. Desirable accuracy is only possible with quality instruments. It is therefore necessary to obtain the instruments of superior quality.
