What is two point perspective?
Two-point perspective uses two vanishing points, connected by a horizontal line. Two-point perspective is useful when developing ideas in 3D.

What is orthographic drawing?
Orthographic projection uses a 2D drawing of each side of an object. Orthographic drawings usually consist of a front view, a side view and a plan view. A drawing board and parallel motion or T-square is used to project one view from another.
