Orthographic Projection

The orthographic projection is a projection from infinity that preserves neither area nor angle. It creates images that have no perspective ? they neither shrink, nor grow with distance. With orthographic projection, the viewpoint or lightsource is an infinite distance away, and there is no vanishing point.

This has the effect of making a view much more symmetric, and easier to gauge relative sizes of parts of large objects. Thus, orthographic projection is usually used for CAD. It is typically also used when precise measurements of the 3D object are required, such as with architectural or scientific purposes.
