An elevation drawing shows what type of planes of a building?

An elevation drawing is specifically designed to depict the vertical planes of a building. It displays the exterior surfaces as seen from a specific viewpoint, illustrating the façade, rooflines, doors, windows, and other architectural elements in a two-dimensional form. Elevation drawings are crucial for providing an understanding of the height, proportions, and overall aesthetic of a structure as they present the vertical relationships and characteristics.

In contrast, horizontal planes are represented in floor plans, which provide a top-down view of the building layout. Diagonal planes are not typically represented in standard elevation drawings, as elevations focus on vertical attributes. Cross-sectional views show a slice through the building, revealing internal elements, but they do not serve the purpose of depicting the building's external vertical surfaces like elevation drawings do. Therefore, the identification of elevation drawings with vertical planes underscores their role in architectural visualization and analysis.
