What term describes the depiction of a single component in technical drawings?

• A. Bloc diagram
• B. Detail drawing
• C. Isometric drawing
• D. Schematic

Answer: (A)

Detail drawing describes a single component in technical drawings. It focuses on that component alone, providing exact dimensions, tolerances, geometric features, surface finishes, threads, holes, and other details needed for manufacturing and inspection. A block diagram shows functional relationships and data flows between system blocks, not the precise physical features of a part. An isometric drawing gives a 3D visualization of the part, useful for understanding shape but not for delivering the exact production information. A schematic maps circuits or system connections, not the component’s physical geometry. Because the depiction of one component with its exact specifications is what a detail drawing provides, that term is the appropriate choice.
