What is the primary purpose of a drawing title block?

• A. To provide project-wide information common to all sheets
• B. To list every individual component and part number
• C. To display the complete wiring schematic
• D. To summarize energy consumption data

Answer: (A)

The drawing title block serves as a centralized source of essential metadata for the whole drawing set. It provides project-wide information that stays consistent across every sheet, such as the project name, drawing title, sheet number, scale, date, revision history, and who drew, checked, and approved the drawing. This makes it easy to identify the drawing, track changes, and ensure all sheets belong to the same project and version. It’s not where you list every component or part number—that belongs in a parts list or bill of materials. It isn’t the place for the complete wiring schematic, which lives in the actual schematic drawings. It also doesn’t summarize energy consumption data, which would come from analyses or reports, not the title block.
