Perspective Drawing is a kind of pictorial drawing or 3D drawing that shows 3 sides of an object seen at one time by the observer's eyes. It is similar with isometric and oblique drawings, however, in perspective drawing, the object's side/s recede/s at angle from the front corners (nearest to the observer's eyes) to the vanishing point/s. One-point perspective, two-point perspective, and three point-perspective are the commonly used types of this pictorial drawing in technical drafting. Moreover, the objects's may be seen at bird's eye-view, man's eye-view, or worm's eye-view. This one is an example of a two-point perspective drawing seen at man's eye view.
