Which view would primarily illustrate horizontal dimensions in architectural drawings?

The plan view is the correct answer because it represents a layout as seen from above, effectively illustrating horizontal dimensions of a building or site. In architectural drawings, the plan view provides a top-down perspective that outlines walls, rooms, and other features, allowing for measurement and understanding of the spatial arrangement in a horizontal plane. This view is essential for understanding the layout and relationships between different spaces within a structure, as it shows the true dimensions without any distortion that may occur in other views.

In contrast, the elevation view focuses on vertical dimensions by depicting the exterior or interior of a structure from one side, emphasizing heights and facade details rather than horizontal layout. The section view provides insights into vertical slices through a building, highlighting different floors and internal components but does not cover horizontal dimensions effectively. Lastly, the perspective view is a three-dimensional representation that captures depth and visual appeal, but it does not present precise horizontal dimensions clearly as a plan view does.
