detailed drawings (called sections and details); a schedule of
drawings; and notes and information (called specifications).
Specifications consist of information such as the quality and
quantity of the materials and the construction methods to be used. A
welldrawn set of prints and wellwritten specifications will help
prevent disagreements and misunderstandings.
The purpose of construction prints is to be exact about shape and
size. They are generally scalesize (with dimensions). It is very
important to know how to read and use construction prints.
1-1. Information on Drawings. Drawings contain different lines,
scales, and symbols. To read drawings, you must be able to interpret
these items. They also include other information in the form of
schedules, notes, and tables.
a. Schedule of Drawings. A schedule of drawings lists the
drawings by number, title, and sheet number (Table 11). It is
usually on the first drawing of a set of prints.

b. General Notes. General notes give additional information that
is needed (Figure 11). For example, item number 3 is for the
carpenter.
Figure 1-1.
c. Graphic and Ratio Scales. Because of the sizes of the objects
being represented, different scales are used for drawings (Figure 12).
