In Fig. 291, let A B D C be the elevation of a pedestal the four sides of which are alike, being in plan as shown by E H G F, Fig. 292. Since the plan is a rectangular figure the miters involved are square miters, or miters forming a joint at 90 degrees. A square miter admits of certain abbreviations, the reasons for which are explained in Problem 3, as well as in Chapter V (Principles Of Pattern Cutting), under the head of Parallel Forms. The abbreviated method which is here illustrated is always used. The plan is introduced only to show the shape of the article, and is not employed directly in cutting the pattern. Space the profiles, shown in the elevation by A C and B D, in the usual manner, numbering the points as shown. Set off a stretchout line, L R, at right angles to the base line C D of the pedestal, through the points in which draw measuring lines. Place the T-square parallel to the stretchout line, and, bringing it successively against the points in the two profiles, cut the corresponding lines drawn through the stretchout. A line traced through these points, as shown by L M O N K, will be the pattern of a side.
