Bill of Materials
a separate list of materials is prepared by an
estimator.
When a BILL OF MATERIALS block is used
on a construction drawing, it is placed directly
above the title block against the right-hand
margin. A bill of materials is a tabulated list of
material requirements for a given project. The size
of the BILL OF MATERIALS block will depend
on the size of the drawing and the number of
material items listed. On most construction
projects, it is impossible to list all items
in a single BILL OF MATERIALS block;
LINE CONVENTIONS
When you are preparing drawings, you will
use different types of lines to convey information.
Line characteristics, such as widths, breaks in the
line, and zigzags, all have definite meanings.
Figure 3-23, taken from DoD-STD-100C, shows
the different types of lines that should be used
therefore, it is omitted from the drawings, and
on your drawings.
