Which of the following is NOT listed as a type of engineering drawing?

• A. Orthographic Projections
• B. Perspective
• C. Site Plan
• D. Preliminary Layout Drawings

Answer: (A)

This question tests understanding of the difference between a drawing type and a drawing method. In engineering drawings, site plans and preliminary layout drawings are concrete types that show layout, scale, and relationships on a project site. A perspective is a visual representation that gives a 3D-like view of the design. Orthographic projections, however, are a technique used to create standard views (like front, top, and side) by projecting lines orthogonally from the object; they’re a method used to generate those views rather than a standalone “type” of drawing. Because orthographic projections are a technique rather than a distinct drawing category, they aren’t typically listed as a type of engineering drawing in the same lineup as site plans, perspectives, or preliminary layout drawings.
