Which view is used to show pit depth in construction drawings?

The correct choice is the section view, which is typically used to illustrate pit depth in construction drawings. This view provides a cut-through representation of the structure, allowing visual access to internal features, including depths or elevations of various elements, which can be critical for understanding the construction details.

In a section view, the dimensions of the pit can be clearly depicted, providing important information about how deep it is and how it interacts with surrounding elements. This clarity assists builders and engineers in visualizing the space and ensuring that construction fits the design specifications.

While elevation views can convey height and some detailing, they do not provide the necessary information about depth in a three-dimensional way. Top views can show layout but lack the depth perspective, and isometric views provide a three-dimensional representation that does not specifically indicate depth measurements in a straightforward manner.
