It will be found that very often a drawing will look better if the finer work, such as the supply pipes, etc., are not shaded, only the fixtures and larger connections being thus treated. In Fig. 61 we give the elevation of the plumbing system for a cottage house, the work being shaded. This is the first complete elevation that we have given as an elevation, but we believe that those who have followed foregoing instructions will have no difficulty in making this drawing. Τ' HE method of shading which we gave in the preceding chapter is easy to handle, and it certainly is of value in making the drawing very clear and distinct. There is also another method of shading, which, however, is much more difficult of execution. This style of shading we show in Figs. 62, 63 and 64, and in order to be able to use it to good effect, considerable experience and practice is necessary. It is used more for ornamental purposes than for practical purposes, but still, no book on drawing would be complete without some attention to it. It is seldom or never that a drawing of any extent would be shaded throughout in this manner, but our readers will find, if they do much in the way of drawing, that its use will often be a valuable aid in showing up apparatus of different kinds, portions of plain drawings that are desired to be brought out with great clearness, etc. In the use of this shading, unere are exact rules that are laid down as to the point which should be shaded heaviest, as well as lightest. It will be sufficient, however, for our purposes to make this instruction very brief and to the point. The results seen in Nos. 1 and 2, of Fig. 62, are obtained by giving the greatest shade effect to the right hand side of the figure, the lightest point being about midway, and the left hand side being shaded somewhat, though not so heavily as the right hand side. These two figures represent solid cylindrical figures. No. 3, a hollow cylindrical figure is shaded in exactly an opposite manner, that is, with the heaviest shading at the left, medium shade effect at the right, but with the lightest point still near the center. No. 4, a horizontal solid cylinder, is shaded N° 3. No 2. FIG. 63. |
