Orthographic Drawings, the typical plan, section and elevations used in drafting also have a lot of potential in the design process. Often, a designer will work back and forth between these drawings to develop a design, as they inform each other. A 3d ‘paraline’ type of drawing is often employed to visualize and test the design that results. The ability to think this way and to employ these types of drawings is a part of any designer’s ‘toolkit’. Actually, it’s fun to play with these drawings after a basic level of skill is acquired.
