This type of drawing is often used in the IPC (illustrated parts catalog)

• A. Hidden line diagrams
• B. Wiring diagrams
• C. Schematic drawings
• D. Exploded views

Answer: (D)

Exploded views show a complete assembly diagram by separating components along their joints, so you can see how parts fit together and in what order they come apart or go back together. This format is especially useful in an Illustrated Parts Catalog (IPC) because it clearly maps each part to its location and orientation within an assembly, often with callouts for part numbers. That makes identifying replacements and understanding disassembly/reassembly straightforward.

Hidden line diagrams reveal internal features without showing how pieces connect, so they don’t convey assembly relationships. Wiring diagrams and schematic drawings focus on electrical connections and functional relationships rather than physical assembly details. Exploded views are the type of drawing commonly used in an IPC because they visually communicate how parts assemble and relate to one another.
