Which of the following drawings would typically depict the TOP view of a part?

The plan view is designed to represent the top view of an object as if it were being seen from directly above. This view focuses on the layout and dimensions of the part in a two-dimensional format, allowing for a clear understanding of its shape and spatial arrangement. In technical drawings, the plan view provides essential details such as the positioning of features and outlines without the distortions found in perspective views.

In contrast, an isometric view presents a three-dimensional representation where all three axes are shown simultaneously, which does not isolate the top perspective. The side view displays the profile of an object from one side, providing depth and height but lacking an aerial perspective. A section view reveals internal features by cutting through the part but does not illustrate the top external contour. Hence, the plan view is uniquely suited to provide a comprehensive depiction of the top aspect of a part, making it the correct choice.
