An artist who practices or works in technical drawing may be called a drafter or draftsman. By using all these instruments we can draw any object on paper . Drawing is one of the major forms of expression within the visual arts. It is generally concerned with the marking of lines and areas of tone onto paper, where the accurate representation of the visual world is expressed upon a plane surface.
