Horizontal dimensions should be read from the bottom of the sheet, and vertical dimensions from the right-hand side of the sheet as in Fig. 16.
6. Lettering.—Lettering is very important for the draftsman, and ability to make good letters is a good asset for anyone. Figure 15 shows the type of lettering that is very frequently used and that is probably most easily made. The strokes for forming the letters are shown by the arrows.
7. Titles.—No drawing is complete without a title which gives such information as the drawing itself fails to impart. Figures 14 and 16 illustrate two different titles, of which the former is the simpler. Figure 16 represents a title such as would appear on an up-to-date shop drawing made in a large office where it would have to be traced, checked, and approved before being blue printed.
