There is also illustrated Lines D which prvide the recommendation for the center punch marks used for orientation of the template layout for center line accuracy. 
     Turning now to  FIG. 11 , there is illustrated a view of the ninety degree ell  7  in the flat position with the orientation used with side  1  of the template for layout of the Figure A on the template. 
       FIG. 12  illustrates a view of a ninety degree ell  7  in the flat position with the orientation used with side  2  of the template for layout of Figure C on the template. While  FIG. 13  illustrates a top view of the ninety degree ell  7  in the flat position with the orientation used with side  1  or side  2  of the template for layout of Figure BB on the template. 
     As seen in the  FIGS. 11 through 13 , numeral  6  illustrates one degree increment graph. 
     Turning now to  FIG. 14 , there is illustrated side  1  of the template, wherein numerals  8  and  9  illustrate a sketch incorporated for reference of values given in  FIG. 16 , which is calculations of odd degree fittings back to back regarding side  1  of the template. The values are illustrated by the numerals  15  and  22  in  FIG. 16 . Returning to  FIG. 14 , there is illustrated an item  10  which illustrates a sketch of odd fittings or any back to back for reference of calculated values given in  14 ,  16 ,  17  and  18  in  FIG. 16 . In item  10 , “A” would represent the desired odd degree fitting; “B” would represent the center line to end dimension of desired fitting; “C” would represent the offset of the desired attached fittings; and “D” would represent end to end dimension of the attached fittings. Further, reference is made to item  11 , which is a chart of calculated values for A, B, C and D of item  10  and actual dimensions for layout of odd fitting in reference to  15  and  22  in  FIG. 16 . 
     Turning now to  FIG. 15 , this represents the embodiment of side  2  of the template used for ninety degree ell with simple odd fittings attached. In item  12  shown on side  2  of the template in  FIG. 15 , there is illustrated a sketch incorporated for reference values given in  19 ,  20 ,  21  and  23  in  FIG. 17 , which is the calculations of an odd degree fitting attached to a ninety degree ell as it relates to side  2  of the template. In  FIG. 15  there is further illustrated item  13 , which is a calculation chart of an odd fitting attached to a ninety degree ell in references to A, B, C and D of item  12  in  FIG. 15 . 
     Turning now to  FIG. 16 , there is illustrated, as was referenced earlier, calculations of odd degree fittings back to back in regard to side  1  of the template. Further is seen column  14  (also labeled column A) which illustrates the degree of the odd fitting. In this orientation, two fittings back to back will be required to obtain given dimensions in column  17  (also labeled column C), for offset and in column  18 , (also labeled column D) for end to end. One can refer to figures C and D of item  10 , which is illustrated in  FIG. 16A . In column  15 , there is illustrated the actual dimensions used for the layout of the outside center line and inside radius of ninety degree ell  7  to obtain the desired single odd degree fitting listed in column  14  (also labeled column A). These were the values incorporated into the one degree increment graphs  6  as illustrated in  FIGS. 11 through 13 . These measurements were incorporated into the design for verification purposes only. 
     Reference is now made to column  16  (also labeled column B) on  FIG. 16 , which illustrates the actual dimensions of center line to end of the desired object refitting listed in column  14  (also labeled column A). One can refer to item B of number  10  in  FIG. 16A . 
     Turning now to column  17  (also labeled column C), this illustrates the offset dimensions of two attached odd fittings listed in column  14  (also labeled column A) and one can refer to C of item  10  in  FIG. 16A . 
     Turning now to column  18  (also labeled column D), this illustrates the end to end dimensions of two attached odd fittings listed in column  14  (also labeled column A). These refer to D of item  10  of  FIG. 16A . 
     As an example, if the known offset is 2″, then the decimal 1.962″ listed in column  17  (also labeled column C) in  FIG. 16  would be the desired value to obtain the odd fittings to be used listed on the same row in column  14  (also labeled column A) in  FIG. 16 . These would be two twenty-seven degree fittings back to back. Also listed in the same row would be the calculated value for end to end listed in column  18  (also labeled column D), dimension 8.172″, and calculated values for the (takeoff) center to end listed in column  16  (also labeled column B) with dimension 2.161″ as seen in  FIG. 16 . 
     Turning finally to  FIGS. 17 and 17A ,  FIG. 17  illustrates side  2  of the template and the calculations of an offset degree fitting attached to a ninety degree ell. There is illustrated column  19  (also labeled column D), which illustrates the center to end dimension of a single odd fitting listed in column  14  (also labeled column A) attached to a ninety degree ell. One can refer to D of item  12  in  FIG. 17A . 
     Turning now to column  20  (also labeled column C), there is illustrated the offset dimension of a single odd fitting listed in column  14  (also labeled column A) attached to a ninety degree ell. One can refer to C in item  12  in  FIG. 17A . Finally, column  21  (also labeled column A) in  FIG. 17 , illustrates the degree of odd fitting. Note in this orientation a single odd fitting attached to a ninety degree ell will be required to obtain given dimensions in column  19  (also labeled Column B) for center to end and column  20  (also labeled Column C) for offset. One can refer to C and D of item  12  in  FIG. 17A .
