Chapter 5 introduces the theory, techniques, and standards of multiviews, which are a standard method for representing engineering designs. The chapter describes how to create one-, two-, and three-view sketches with traditional tools and CAD. Also described are standard practices for representing edges, curves, holes, tangencies, and fillets and rounds. The foundation of multiviews is orthographic projection, based on parallel lines of sight and mutually perpendicular views. Also introduced in this chapter are visualization techniques that can be used to help create and interpret multiviews.
