Fig. 56. Here, the figure BX only, would be given, and it would beassumed to touch the picture plane. We first produce thevanishing lines DX and AC to meet in C.Y., then drawC.Y. S perpendicular to B.L., and make it equal to height ofspectator; then draw H.L. parallel to B.L. through C.Y.;next take a point MP at a distance to the left equal to theheight of spectator and his distance away, combined; thenjoin MP with C, and produce it to base at E. Then, scalebeing given, find BA, AD and AC, the dimensions of the solid,and AS will show its distance to the left. (Pig. 56.) 94 DRAWING. Perspective Hffect. This consists in showing merely the appearance of an objectwhen placed in a certain position. The dimensions and dis-tance of the object are not taken into account.
