Which view shows the relationship of a structure's height?

The elevation view is the correct choice because it presents a vertical representation of a structure, clearly illustrating its height and the detailing of its vertical features. Elevation drawings are essential in architecture and engineering as they allow viewers to see how tall a building or structure is, including the arrangement of windows, doors, and other vertical elements. By using an elevation view, one can assess the proportions of a structure in height relative to its width and depth, making it a crucial tool for understanding the spatial arrangement and design.

In contrast, the plan view depicts a horizontal layout from above, showing the arrangement of rooms and spaces at a given level, but it does not convey any information about height. The side view could refer to a variety of perspectives, but it is not as specifically defined in architectural terms as an elevation view. Perspective view provides a three-dimensional representation with depth and field, which, while visually impactful, does not explicitly represent height in a definable manner like an elevation drawing does.
