Which statement best describes a sectional view?

• A. A top view of the roof plan
• B. An external elevation of the facade
• C. A vertical view of a building as if it were cut into two parts
• D. A 3D isometric representation

Answer: (C)

A sectional view is a vertical slice through a building, shown as if the structure were cut into two parts so you can look at the interior. This reveals how spaces relate to each other, how rooms stack above one another, and interior construction details like wall assemblies, stairs, doors, and floor levels that aren’t visible from the outside. It’s created by imagining a cutting plane and removing one side to expose the interior, which is why you see interior features and dimensions in a way a straight exterior view cannot show. This differs from a top view of the roof plan, which looks down from above at the layout of the roof; an external elevation shows the exterior façade from the outside; and a 3D isometric view provides a three-dimensional perspective without slicing through the building.
