Which of the following is a vertical view of a building as if it were cut into two parts?

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

Answer: (A)

A sectional view is a vertical slice through a building, as if you cut it with a plane and pull the halves apart to reveal what’s inside. This type of drawing shows interior construction, stairwells, room heights, and details hidden behind walls—information you can't get from looking at the exterior or from a top-down shot. A plan view is a horizontal cut looked at from above, not a vertical cross-section. An elevation shows the exterior vertical faces of the building, not the internal arrangement. An isometric is a 3D representation that doesn’t depict a true cut to reveal internal features. So the vertical view produced by a cut through the building is a sectional view.
