Which drawing shows a vertical slice through the building, revealing walls, floors, and stair arrangement?

• A. Plot survey
• B. Floor plan
• C. Plot plan
• D. Sectional view

Answer: (D)

A sectional view is drawn as a vertical cross-section through a building, revealing interior elements like walls, floor levels, and how stairs connect different floors. This type of drawing cuts through the structure to show what lies inside and how the different levels relate to one another, which is exactly what the question describes.

A floor plan, by contrast, shows the layout from above on one level—rooms, doors, and walls seen horizontally. A plot plan presents the building’s footprint and site features on the property, not the interior. A plot survey focuses on property boundaries and measured locations on the land.
