Orthographic projection is used to represent a three‑dimensional object using what?

• A. Several Two-Dimensional Views
• B. A Single Perspective
• C. Only Isometric View
• D. Exploded View

Answer: (A)

Orthographic projection communicates a three-dimensional object by drawing it in multiple two-dimensional views on perpendicular planes. Each view—typically the front, top, and side—shows the true size and shape of the object’s features in that particular orientation, so measurements remain accurate. Because depth cannot be captured in a single flat view, using several views lets you know length, width, and height all at once when you combine them. A single perspective would mimic how the object looks from one viewpoint, with lines converging toward a vanishing point and apparent sizes changing with distance, which makes precise manufacturing measurements unreliable. An isometric (or other axonometric) view presents a 3D impression in one image but distorts true dimensions and angles. An exploded view shows components separated to illustrate assembly, not the standard way to represent the full 3D shape with accurate measurements.
