Fiom thissection the pattern for the com-mon bar can be obtained withoutthe plan, as follows:. Fig. 176. At right angles to D 4 draw the line I J upon whch place thestretchout of the section E as shown by similar figures on I J. Throughthese small figures, and at right angles to I J, draw lines, and intersecttliem by lines drawn at right angles to D 4 from similarly numberedintersections 1 to 6 on the curb and 1 to 6 on the inside a line tlirough points thus obtained; then A* B* C* D^ will be the 226 SHEET METAL WORK h: pattern for the common bar in a hipped skvUght. The same methodwould be employed if a pattern were developed for a flat or a hght. From this same half section the pattern for the curb isdeveloped by taking the stretchout of the various corners in the curb,abS 4 c d e and /, and placing them on the center line A B as shownby similar letters and figures. Through these di\asions and at rightangles to A B draw lines which intersect with lines drawn at rightangles to C 4 from similar points in the curb section a f. Trace a linethrough po
