These receding lines that converge in the horizon line outsidf 73 74 AUGSBURGS DRAWING. of the center of vision are called oblique horizontal receding because they are at an oblique angle with the pictureplane; horizontal because parallel with the ground plane; andreceding because they pass from you— recede. Receding lines 1, 2 and 3 are horizontal receding lines, andreceding lines 4, 5, 6, 7, 8, and 9 are oblique horizontal receding. It is not practicable or desirable to use these vanishing points inordinary drawing., for the following reasons : (1) Because one of these points is and usually both areoutside of the paper on which the drawing is made, and thus too. far away. (2) Their use draws the attention from the object andlessens the range of the judgment. (3) .Their use is not practical,satisfactory or necessary. But while the above is true, a knowledge of these points is ofgreat aid to the judgment in determining the direction of lines andsurfaces. Box A is said to be drawn in parallel perspective and Box B inangular perspective. Lines and Models.— Place before you a common pasteboardbox in the position of Fig. 2 and observe the three sets of lines1, 1,1,1; 2, 2, 2, 2 ; 3, 3, 3, 3. The first set are vertical and AUGSBURGS DRAWING. 75 parallel. The sets marked 2, 2, 2, 2, and 3, 3, 3, 3, are receding,and consequently converge slightly, hut in the drmving they shouldnot appear to converge^ but should appear parallel — thei/ shouldappear natural. Draw all objects with light lines and then finish with the receding lines longer than the edge of the object so as tojudge more accurately of their cor
