Using a Miter Line
A miter line (OE in the figure) offers a convenient method of laying out a third view while you are in the process of drawing two views. Place the miter line (OE) to the right of the top view at a convenient distance, keeping the appearance of a balanced drawing. Draw light projection lines from the top view to the miter line, then vertically downward from the point where they intersect the miter line. Using the front view, draw horizontal projection lines to the right, intersecting the vertical projection lines. The result of this procedure is the outline and placement of the right side view.
