## Figure Showing The Bottom Edge Of A Hole In An Isometric Drawing

To determine exactly if and how much of the bottom edge of the hole should be drawn, locate the center point of the hole on the bottom surface and draw the hole by using the same procedure you used for the hole on the top surface. If the hole drawn on the bottom surface appears within the hole on the top surface, it should appear on the finished drawing. If the hole drawn on the bottom surface does not appear within the hole on the top surface, it should not appear on the finished drawing. Figure 49 (on the previous page) presents a sample problem that illustrates this procedure.

d. Round and Irregular Surfaces. Figure 50 is a sample that requires you to create an isometric drawing from given orthographic views that contain a round surface. To make an isometric drawing of a round surface, use either an isometric template for a guide or the point method.
