Which view type provides a 2D representation used for maps, plans, cross-sections, and elevations?

• A. Perspective View
• B. Top View
• C. Isometric view
• D. Orthographic view

Answer: (D)

In drafting and 3D workflows, 2D representations used for maps, plans, cross-sections, and elevations come from orthographic projection. This approach projects the 3D object onto a plane with parallel lines, so measurements stay true to scale on each view. That means a plan (top view), an elevation (front or side view), and a section (a cut view) can all be drawn accurately without perspective distortion, which is essential for construction and architectural documents. Perspective views simulate how things appear to the eye, with depth and vanishing points, which distorts size as objects recede—not suitable for precise drawings. Isometric views show three dimensions in a single view but don’t preserve true scale for each axis the way orthographic projections do, so they’re used more for conceptual visualization than exact plans. The broad view type that encompasses all the standard 2D drawing directions for maps, plans, cross-sections, and elevations is orthographic view.
