Drawing is a technique of visually representing, in two dimensions, characters, landscapes or objects. The word was written indifferently design or drawing, involving the notion of intention, of project, in a work of greater scope, in architecture, in painting, in engraving until the seventeenth century.
Linear drawing represents objects by their contours and some characteristic lines; Beyond this limit, the drawing develops by representing the shadows, for example by hatching, incorporates colors, and joins, without a clear transition, the painting.
