technical drawings
Precise design illustrations
Technical drawings are precise diagrams that communicate how something should be built, assembled, or manufactured.
Unlike artistic sketches, they follow standardized conventions for dimensions, scales, and symbols so engineers, architects, and fabricators can interpret them consistently: The technical drawings showed every bolt and weld.
Also called engineering drawings or mechanical drawings.
