The reference block can be extremely helpful in tracing down additional information on the system or component. 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 third area of the title block is the reference block. These names can also help in the resolution of a discrepancy between the drawing and another source of information.įigure 1 Title block for engineering drawing This information can be invaluable in locating further data on the system/component design or operation. The second area of the title block contains the signatures and approval dates, which provide information as to when and by whom the component/system was designed and when and by whom the drawing was drafted and verified for final approval.

A title block is divided into several areas as illustrated by Figure 1 below. The title block of a drawing, usually located on the bottom or lower right hand corner, contains all the information necessary to identify the drawing and to verify its validity. The information contained in the fifth part or the drawing itself is covered in unit 1. Failure to understand these areas can result in improper use or the misinterpretation of the drawing. The ability to understand the information contained in these areas is as important as being able to read the drawing itself. The first four parts listed above provide important information about the actual drawing.
