Which of the following describes a horizontal drawing of a structure at a given level such as ground floor, basement, or roof?

• A. Elevatio n
• B. Section
• C. Floor plan
• D. Isometric

Answer: (C)

A floor plan is a horizontal drawing viewed from above that represents a specific level of a structure. It shows how spaces are laid out on that level, including walls, doors, windows, stairs, and installed fixtures, so you can see how rooms relate to each other and how circulation works. This view is ideal for understanding the arrangement on ground floors, basements, or even roof-level plans, since it captures the horizontal relationships and access paths necessary for construction, egress, and safety planning.

An elevation, by contrast, is a vertical view of a wall or façade, depicting height and exterior features rather than the internal layout. A section is a vertical cut through the building that reveals internal relationships and heights along a line. An isometric is a 3D representation showing form and perspective rather than a precise horizontal layout of a single level.
