Which drawing contains views projected onto two or more orthographic planes?

• A. Perspective Sketch
• B. Pictorial Sketch
• C. Oblique Sketch
• D. Multi-View Drawing

Answer: (D)

A drawing that shows views projected onto two or more orthographic planes uses orthographic projection to present the object from multiple directions, typically front, top, and side. Each view lies on a plane perpendicular to the others, so the size and shape of features are true in their respective views. This approach is essential for manufacturing because it communicates exact dimensions and relationships without perspective distortion. In contrast, a perspective sketch creates depth from a single viewpoint with lines that converge toward a vanishing point, which distorts true size. A pictorial sketch aims to show the object as a whole in 3D but doesn’t provide separate true-size views on perpendicular planes. An oblique sketch presents depth by slanting it relative to the front view, but it still isn’t a set of views on multiple orthographic planes.
