Freehand sketching an introduction
Embed Size (px)
Freehand drawing and sketching is a means of quickly putting your thoughts down on paper. Freehand drawing and sketching differs from instrumental drawing primarily in the amount of time and accuracy required. In appearance, the completed freehand drawing is entirely different from the clean-cut precision of a mechanically ruled or computer generated working drawing, it has a rough and natural appeal, but should be clear, concise and suitable for the intended purpose. A poorly presented freehand drawing is unlikely to be appreciated, understood, or accepted.
