Which of the following lists the five elements of a sketch?

• A. Heading, diagram area, legend, title block
• B. Diagram area, legend, scale and direction notations
• C. Heading, diagram area, legend, title block, scale and direction notations
• D. Heading, legend, scale, and direction

Answer: (C)

In sketch documentation, five components work together to make the drawing clear, usable, and trustworthy. The heading provides essential context like the case, location, date, and who prepared the sketch, establishing provenance. The diagram area is the actual drawing—the spatial representation of the scene with the layout and measurements visible. The legend decodes the symbols used on the diagram so anyone reviewing it understands what each mark represents. The title block records key metadata about the drawing, such as author, date, and relevant identifiers, aiding reproducibility and custody. The scale and direction notations indicate the size relationships and orientation (usually a north arrow), allowing measurements to be interpreted correctly and compared to other evidence. Together, these five elements ensure the sketch can be understood, verified, and used in analysis and courtroom presentation. If any are missing, the drawing loses essential information about context, accuracy, or provenance.
