Which type of drawing is primarily used in the elevation phase to show height and design features?

In architectural design, elevation views are critical as they represent the vertical dimensions of a building. This type of drawing illustrates the exterior facade's height, design features, and materials used, providing a clear view of how the structure appears from a particular angle. It captures elements such as windows, doors, roof lines, and other architectural details at scale, which are essential for visualizing the final appearance of a building.

These views serve several purposes, including communicating design intent to clients, contractors, and other stakeholders, as well as aiding in obtaining necessary permits. They help to conceptualize how a structure will interact with its environment and how different design elements come together aesthetically across various elevations.

In contrast, plan views depict the layout of spaces from a top-down perspective and do not convey height. Section views provide insights into the internal composition of a structure, detailing how different levels relate vertically, but they do not focus on the external appearance. Detail views zoom in on specific construction elements, providing intricate information but lacking the broader perspective of height and design aesthetics. Thus, elevation views stand out as the primary tool for showcasing design features related to height and external design in architecture.
