An isometric hole template may be conveniently used as a guide for drawing the hole size for which it is cut. To align the template for drawing, first draw in the hole center lines, then align the guidelines printed on the template adjacent to the desired hole with the center lines on the drawing. If you are still unsure of how to position the template, draw in the center lines and the major and minor axes of the ellipse as shown in figure 44 (on the following page). Then align the template with the four intersections formed by the center lines as they cross the major and minor axes (labeled points 1, 2, 3, and 4 in figure 44) and draw in the ellipse.
