What does an assembly drawing show?

• A. A drawing that shows only the largest subassembly.
• B. A drawing that shows all the components of a part in an exploded form.
• C. A drawing containing only a single view.
• D. A drawing used to designate material specs.

Answer: (B)

An assembly drawing shows how the pieces of an entire unit fit together. It lists every component that makes up the assembly and often uses an exploded view to reveal how parts relate, orient, and fasten to one another, as well as the order in which they go together. This type of drawing helps technicians understand how to assemble, disassemble, and inspect the unit, and it often accompanies a bill of materials that lists each part and quantity. It isn’t limited to showing only the largest subassembly, nor is it restricted to a single view—the drawing can include multiple views or an exploded representation to communicate how parts connect. Material specifications, meanwhile, are usually found on separate documents rather than on the assembly drawing itself.
