Which 3D drawing method gives drawings depth and can be used to design in 3D?

• A. Isometric
• B. One Point Perspective
• C. Two Point Perspective
• D. Thick Thin line

Answer: (B)

One-point perspective creates depth by using a single vanishing point on the horizon. All lines that go back into the scene recede toward this point, while vertical edges stay vertical. This mirrors how we naturally see space when looking straight at something, so drawings feel three-dimensional and realistic. It’s especially useful for designing in 3D because you can place features on a front-facing view and extend them back into space with a consistent sense of scale and depth, ideal for interiors, furniture, or product designs viewed head-on. Other methods change how depth is shown—isometric uses parallel lines with equal foreshortening for a more technical look, two-point perspective uses two vanishing points for angled views, and thick-thin line is about line weight rather than creating depth.
