An orthographic drawing system is a projection that represents three dimensional objects in two dimensions. Orthographic drawings usually consist of a front view, a side view and a plan. The difference between orthographic and perspective is that the former tries to create the sense of depth and distance while orthographic drawing removes the notion of complexity. Orthographic projection refers to a method of projection in which an object is depicted using parallel lines to project its shape onto a plane.
