Fig. 296 - The Pattern for a Vase, the Plan of which is a Heptagon.

In Fig. 296, let E L P G be the elevation of the vase, constructed in such a manner that one of its sides will be shown in profile. In line with it draw the plan, placing it so that, it shall correspond with the elevation. Space the profile L P in the usual manner, and from the points in it drop lines crossing one section of the plan, cutting the miter lines R S and H V, as shown. Lay off a. stretchout, A B, at right angles to the side of the plan corresponding to the side of the vase shown in profile in the elevation. Through the points in it draw the usual measuring lines. Place the T-square parallel to this stretchout line, and, bringing it successively against the points in the miter lines, cut the corresponding measuring lines, as shown. A line traced through these points, as shown by K O

W U, will be the pattern of one of the sides of the vase.
