In ornamental cornice work, it often ha])pens that tapering mould-ed panels are used, a plan and elevation of which are shown in Fig. 285. 296 SHEET METAL WORK 211 By referring to the plan, it will be seen that the four parts b a, a &, 6 a,and a b are symmetrical; therefore, in practice, it is necessary only todraw the one-quarter plan, as shown in Fig. 286, and omit the eleva-tion, since the height d e (Fig. 285) is known. Thus, in Fig. 286, drawthe quarter-plan of the panel, no matter what is its shape, as shown
