Which statement best describes what a sectional drawing reveals?

• A. A sectional drawing shows relationships between floors, heights of spaces, and construction details; reveals stairs, levels, and structural elements.
• B. A plan view showing layout from above.
• C. An isometric drawing primarily used for furniture layout.
• D. A detail drawing that shows only the roof connections.

Answer: (B)

A sectional drawing reveals vertical relationships inside a building by slicing through it to show what sits above and below a chosen plane. This view makes clear how spaces relate in height—from floor to ceiling and from one level to the next—and how stairs connect different floors. It also exposes structural elements like floors, beams, columns, and walls, along with how roof and floor assemblies tie into the surrounding structure.

This is different from a plan view, which looks down from above to show layout, walls, doors, and rooms; an isometric drawing presents a 3D view used for spatial understanding or furniture layouts; and a detail drawing focuses on a small area to illustrate particular connections or components.
