Which term denotes a technical drawing showing multiple 2D views (front, side, plan) used to communicate accurate dimensions for manufacture?

• A. Concept sketch
• B. Isometric drawing
• C. Orthographic drawing
• D. Primary research

Answer: (C)

This item tests understanding of a technical drawing that communicates precise measurements for manufacture by using several flat views. An orthographic drawing uses repeated views—front, plan (top), and side—each projected onto its own plane so the object’s true size and shape can be seen from different directions. With these views, every dimension needed to reproduce the part is clearly indicated, making it straightforward for a maker to fabricate accurately. Concept sketches are rough, informal drawings that aren’t meant to convey exact measurements. Isometric drawings present a single 3D view to give a sense of shape, but they don’t show true dimensions in each view for manufacturing. Primary research isn’t a drawing at all; it refers to gathering information.
