mities of the diameters E, S, T, and W, are eight points in the ellipse which is the shadow of the given circular plane on Y. A similar construction is followed for find- ing the shadow on Y of a circular plane parallel to H. Fig. 43. 90. Problem XX5H. To construct the shade line of a cylin= der… … (parallel to its axis) of a circular cylinder whose axis is either perpendicular, or parallel to the ground line. Let cl = the distance, in the elevation, between the projection of the axis of the cylinder and the projection of the visible shade element. Let Z»=the distance between the axis of the…
