Blueprint Compositions, Continued Reference Reference numbers refer to numbers of other drawings. A dash and a numbers number show that more than one detail is shown on a drawing. When two parts are shown in the detail drawing, the print has the drawing number plus a dash and an individual number. Dashes and numbers identify changed or improved parts and right- or left-hand parts. Left-hand parts are usually depicted in drawings. Some drawings use RH or LH for right- or left-hand parts. Others use even numbers for right-hand drawings and odd numbers for left-hand drawings. Reference numbers appear in the title block and they may also appear within the drawing near the parts they identify. Some reference numbers use a leader line to show the drawing and dash number of the part. Others use a 3/8-inch diameter circle around a dash number with a leader line to the part. Figure 1-38 is an example of reference numbers. Figure 1-38.—Reference number location. 1-50 Continued on next page
