Abstract: This chapter discusses the types of projection. The perspective method of illustration is the simplest and easiest to understand. It has been used by artists for hundreds of years and is still used for illustrating articles in journals where a photograph would be unsuitable. Perspective drawing means putting down on paper what is seen when looking at an object with normal vision. when an object moves away from it, it appears to get smaller. Parallel, horizontal lines appear to get closer together and vanish on the horizon. Pictorial drawings are useful to the student when models for drawing exercises are not available, because from them one can visualize what the object looks like. One form of pictorial drawing is known as isometric, in which all lines are drawn either vertically or at 30° to a horizontal line. Orthographic projection is a method of illustrating an object by drawings and views projected by lines perpendicular to the plane of projection, or in simpler terms "projecting views at right angles to one another."
