blueprint reading
Decoding technical drawings
Blueprint reading is the skill of interpreting technical drawings—architectural plans, engineering schematics, or manufacturing diagrams.
It involves understanding symbols, dimensions, scales, and notations that specify how something should be built or assembled: Blueprint reading is essential for construction workers and machinists.
The term persists even though most technical drawings are now digital rather than actual blueprints.
