Which term refers to orthographic drawings of the components of an assembly containing details just about that component?

• A. Perspective
• B. Physical modelling
• C. Haptic technology
• D. Part drawings

Answer: (D)

Part drawings are the orthographic drawings that focus on a single component. They show the component from multiple standard views with precise dimensions, tolerances, materials, and surface finish notes, so someone can manufacture and inspect that part on its own. This makes them different from assembly drawings, which depict how multiple parts fit together in an assembled product. The other terms describe different ideas—perspective drawings are 3D representations, physical modelling refers to building a tangible model, and haptic technology relates to touch-based feedback—so they don’t apply to detailing just one component.
