Third Area of the Title Block
Figure 1 Title Block
The third area of the title block is the reference block. The reference block lists other
drawings that are related to the system/component, or it can list all the other drawings that
are cross-referenced on the drawing, depending on the site's or vendor's conventions. The
reference block can be extremely helpful in tracing down additional information on the
system or component.
Other information may also be contained in the title block and will vary from site to site and
vendor to vendor. Some examples are contract numbers and drawing scale.
