Book excerpt: Excerpt from Working Drawings and Drafting-Room Kinks It is not the business of the mechanical draftsman, however, to make pictures, and he seldom has occasion to draw perspective views. He has to convey his ideas by simpler methods than this, and in making working drawings uses what is called Orthographic Projection, or simply, projection. His drawing may not always look like the object, from the pictorial standpoint, since certain conventional figures and methods are adopted to represent machine parts, which can be drawn much quicker in this way than if their true form were reproduced. Thus, it is not customary to draw screw threads in the way in which they actually appear to the eye; an easier and quicker method of representing them is adopted, and the same is true of.
