For the numerator and the denominator of a fraction use figures about two-thirds as high as the other figures, making the fractions about 50 per cent taller than the integers. Do not crowd the figures; if the space allotted to them is necessarily limited place the figures a short distance away (still parallel to the dimension line), and use a curving freehand line to serve as a pointer. Do not, however, try to save figures by using two pointers extending from the same figure to two equal spaces, --each space must have its own figures. See PI. 12. Express distances less than 1 ft. thus: f," if," io." Express distances between 1 ft. and 2 ft. thus: 125," 23!." (Structural draftsmen prefer I'-oj," I'-nf"). Express distances greater than 2 ft. (unless otherwise directed), thus: 2'-o," 3'-7," io'-of." (A few draftsmen use 3FT.-6.") Diameters of pipe and shafting, lengths of wheel treads, etc., are usually expressed in inches. Fractions used must be multiples of one sixty-fourth of an inch, as W, A," I," etc. (never A," They must be reduced to their lowest terms, as not Make the dividing line of a fraction a horizontal line, never a slanting one; otherwise it would be easy to confuse such dimensions as iyg" and Where extreme accuracy in construction is essen tial, express a distance in inches and hundredths or thousandths of an inch, as 2.72," 10.035." Indicated dimensions take precedence over scaled distances, in case the two do not agree. There is more need for clear and unmistakable figures than for clear and unm...
