Which type of drawing focuses specifically on the details of a single part, showing its shape accurately?

A detail drawing is specifically designed to focus on the intricate aspects of a single part, providing an accurate representation of its shape and dimensions. This type of drawing highlights features such as contours, materials, finishes, and tolerances, which are critical for manufacturing or construction processes. By isolating one component, detail drawings ensure that all necessary information is clearly presented, allowing for a precise understanding of the part's specifications.

In contrast, an overview drawing typically presents a broader view of multiple components, which may not provide the extensive detail needed for a single part. Sectional drawings visualize the interior features of an object by showing cut-through views, which can be helpful but do not exclusively detail one part's shape. Lastly, assembly drawings depict how multiple components fit together, lacking the singular focus on the shape and specifications of one individual part. Therefore, the detail drawing is the most accurate response to the question concerning shape representation.
