ame face is at 60° to the H.P. and at25° to the V.P. The preUminary plan shape and elevation for levels are shownat (i), and the compound angle problem for the edge BC is worked out as in Fig. 26,the arrow line showing the direction for &2C2 in the required plan. In the illustration Fig. 31 a… … Fig. 31, the V.P., and is therefore fully visible as a foreshortened hexagon, while dottedlines have to be used for part of the outline of the lower end. In working thecompound angle problem it is only necessary to find the plan direction, markedwith the arrow line in the figure, as the elevation…
