What is the class of working drawing that is the description/depiction of a single part?

• A. Installation drawing
• B. Assembly drawing
• C. Detail drawing
• D. General drawing

Answer: (C)

When a drawing is meant to describe how to make one specific part, the type used is the detail drawing. It lays out the exact geometry, all dimensions, tolerances, finishes, materials, and any manufacturing notes needed to produce that part. It often includes multiple views or sectional views to reveal every feature such as holes, threads, radii, and surface finishes, so the part can be manufactured exactly as intended.

This differs from an assembly drawing, which shows how several parts fit together and interact, not the precise making of a single part. An installation drawing focuses on placing the part or system in its operating environment, and a general drawing covers broader project information rather than the specifics of one part.
