In Fig. 289, let A B K and B K B be the angles of the miters at the foot and peak of a gable. Draw profiles of the required molding in correct relation to both the horizontal and inclined moldings, as shown at H and H1, through the angles of which draw the other parallel lines necessary to complete the elevation. Their intersection at the base of the gable produces the miter line B C, while the miter line at the top of the gable is a vertical line, because the two sides of the gable, K B and K R, are of the same pitch. The profile H is so placed as also to represent the return at, the side at its proper distance from B. Divide the profile H in the usual manner into any convenient number of equal parts. Place the T-square parellel to the lines in the horizontal molding, and, bringing it successively against the points in the profile, cut the miter line B C, as shown. At right angles to the lines of the horizontal cornice draw the stretchout E F, through the points in which draw the usual measuring lines, as shown. Reverse the T-square, letting the blade lie parallel to the stretchout line E F, and, bringing it against the several points of the profile H, cut the corresponding measuring lines. Then a line traced through these points of intersection, as shown from G to V, will be the pattern of the end of the horizontal cornice mitering with the return. In like manner, with the T-square in the same position, bring it against the points in the miter line B C, and cut corresponding measuring Lines drawn through the same stretchout. Then a line traced through the points of intersection thus obtained, as shown by T U, will be the pattern of the end of the horizontal cornice mitering against the inclined cornice. Divide the profile H1 into any convenient number of equal parts, all as indicated by the small figures. Through these points draw lines cutting the miter line B C, and also the miter line K L at the top. At right angles to the lines of the raking cornice place a stretchout, E1 F1, of the profile H1, through the points in which draw the usual measuring lines, as shown. Place the T-square parallel to this stretchout line, and, bringing it successively against the points in B C and K L. cut the corresponding measuring lines, all as indicated by the dotted lines. Through the points thus obtained trace lines, as indicated by M N and O P. Then M N will be the pattern for the bottom of the raking cornice mitering against the horizontal, and O P will be the pattern for the top of the same. The pattern shown at G V will also be the pattern for the return mitering with A D of the elevation, it being necessary only to reverse it and to establish its length.
