Which type of drawing indicates the height of an object but not its depth?

An elevation drawing specifically represents a vertical plane of an object, showcasing its height and width while omitting depth. This type of drawing provides a clear view of the facade or exterior of a building, structure, or object, allowing viewers to discern vertical dimensions without the complexity introduced by depth. Elevation drawings are crucial in architecture and construction, as they help in visualizing how a design will appear from different angles and in understanding proportionality in height relative to other objects or the ground.

In contrast, a blueprint is a detailed technical drawing that can include depth, width, and height, primarily used for construction and engineering purposes. A section drawing is more about providing insight into the internal features of an object by slicing through it, thus illustrating how the different layers and components interact within an object. An isometric drawing is a three-dimensional representation, which, while effective for depicting depth, height, and width together, does not serve the same purpose as an elevation drawing. This is why elevation drawings stand out as the correct choice for indicating height without showing depth.
