What is defined as a dimensioned, working drawing of a single part?

The correct choice is a detail drawing, which is specifically defined as a dimensioned, working drawing of a single part. Detail drawings provide all the necessary information for the fabrication of a single component, including dimensions, material specifications, and any necessary notes that guide the manufacturing process. This ensures that manufacturers clearly understand the required features and tolerances of the part.

Other types of drawings serve different purposes. An assembly drawing shows how multiple parts fit together as a whole, rather than focusing on a single part. A section view provides a view of a part as if it has been cut through, revealing internal features rather than providing a complete picture of one component. An exploded view illustrates how parts fit together by separating them in space, which is useful for understanding assembly but does not give the detailed specifications of an individual part. Therefore, detail drawing is the most appropriate term for a drawing that presents the necessary information about a single part.
