Vertical view of a building as if it were cut into two parts; intended to show the internal construction of each assembly is known as

• A. Sectional View
• B. Plan View
• C. Elevation View
• D. Isometric View

Answer: (A)

A sectional view is a vertical cut through a building, intended to reveal internal construction of each assembly. This type of drawing lets you see how walls, floors, and partitions are put together, including layers of materials, studs, joists, insulation, and other hidden components that aren’t visible from the exterior. It’s especially useful for assessing fire-rated assemblies and how different components meet specifications.

By comparison, a plan view shows the layout from above, a plan of rooms and spaces; an elevation view shows the exterior faces; and an isometric view provides a 3D perspective that illustrates form but doesn’t depict a true interior cross-section.
