What is the primary purpose of architectural drawings?

The primary purpose of architectural drawings is to convey the size, shape, layout, and finishes of a building. These drawings serve as a visual representation of the design intent and are essential for communicating information to various stakeholders involved in a construction project, including architects, engineers, and contractors. Architectural drawings detail how a building is constructed and finished, allowing for an understanding of the spatial relationships and overall aesthetic of the structure. They are fundamental documents that guide the construction process, ensuring that all parties share a common understanding of the envisioned design.

While other types of drawings, such as those for mechanical, structural, and electrical systems, are important in their own right, they do not encapsulate the comprehensive overview of a building's design that architectural drawings provide. Thus, the correct answer emphasizes the overall vision of the building's design rather than just specific systems or components.
