What does an assembly drawing show?

• A. How mating parts fit together
• B. The material specifications of each part
• C. The surface finish requirements
• D. The assembly sequence

Answer: (A)

An assembly drawing is used to convey how components come together in the finished product. It shows the relative positions and orientation of each part, where mating surfaces, holes, pins, and fasteners line up, and how parts connect through joints so the final assembly fits and functions as intended. This view helps ensure proper clearance, alignment, and interaction between parts, and it often indicates where fasteners and subassemblies belong. Material specifications are usually found on part drawings or in a bill of materials, not on the assembly view, and surface finish requirements are typically specified on the individual part drawings rather than as the primary purpose of the assembly drawing. An exploded view can illustrate the assembly sequence, but the main function is to depict the fit and relationships of parts in the assembled state.
