Where on a drawing would you locate the specific tolerances for a block in the design?

• A. The header
• B. The title block
• C. The data block
• D. The revision block

Answer: (B)

The main idea here is where drawing-wide tolerances are defined. General tolerances—that apply to most dimensions on the sheet unless a specific one is called out—are recorded in the title block. This makes the tolerancing policy clear and consistent for anyone reading the drawing. The header, data block, and revision block aren’t the standard places for tolerances. Any particular dimension or feature would show its own tolerance near the feature if a deviation from the general tolerances is needed, but the title block sets the baseline rules for the entire drawing.
