technical drawing
Precise design illustration
Technical drawing is the practice of creating precise, detailed diagrams that communicate how something should be built, assembled, or manufactured.
Unlike artistic sketches, technical drawings follow standardized conventions for dimensions, scales, and symbols so that engineers, architects, and machinists can interpret them consistently.
The term covers everything from architectural blueprints to mechanical schematics to electronic circuit diagrams.
The contractor worked from the technical drawings to frame the building.
