Draw (Fig. 67) E' E 6 A 6' one quarter of the plan of the body. Divide the quadrants E h, E' b', each into the same… … join d d', c c'. Through E' draw E' F perpendicular to E' E and equal to the given height of the body. From E' along E'E mark off E' D, E C, and E'B respectively equal to dd', c c', and h h' ; and join E F, D F, C F, and B F; then E f' D F, C F, and B F will be the true lengths of E E', d d', c c',…
