Architectural drawings are used to illustrate building designs and provide instructions for construction. They include floor plans, elevations, sections, and details. Floor plans show the arrangement of rooms from above while elevations display the external appearance of each facade. Sections cut through the building to reveal interior construction. Details focus on specific elements at a larger scale. Architectural drawings are produced to scale using drafting tools or computer-aided design software. They allow architects to communicate designs to clients and facilitate building.
