The term 'cross-section' in building plans refers to a view that illustrates the interior specifics of a building as if the structure has been cut through. This type of drawing provides important insights into the layout and organization of spaces within a building, showing details such as walls, doors, windows, and the relationship between different levels. It allows architects, builders, and engineers to communicate and analyze the internal structure effectively, serving as a critical tool for understanding the design intent and functionality of the space.

The other options do not adequately capture the concept of a cross-section. For instance, a view from above is considered a plan view, which differs from a cross-section. Landscaping designs focus on external features rather than the internal specifics, while representations of structural components generally refer to details about the materials and construction methods used, rather than a cut-through view revealing internal layouts.
