What do most common types of architectural plans represent?

Most common types of architectural plans primarily represent 2D representations. This includes drawings such as floor plans, elevations, and sections, which provide a detailed view of the layout and structure of a building. These 2D plans are essential for conveying information about dimensions, materials, and the arrangement of spaces in a building project. They serve as the foundation for communication between architects, builders, and clients, allowing for a clear understanding of the design before construction begins.

While 3D perspectives, floor elevations, and structural details are important aspects of architectural design, they are not the primary representation format in most standard architectural plans. 3D perspectives provide a visual understanding of how a space will look but are not typically used for construction documents. Floor elevations show vertical heights and may be part of the details, but they don't provide the comprehensive layout found in 2D plans. Structural details are often included in technical drawings but are not the main type of plan used to represent the overall architectural design.
