T-squares
Architect's drawing tools
A T-square is a drafting tool shaped like the letter T, with a long blade attached at right angles to a shorter crosspiece.
The crosspiece hooks over the edge of a drafting table, allowing the blade to slide up and down while staying perfectly horizontal.
Used for drawing parallel lines and as a guide for triangles and other tools: She lined up the T-square and drew a clean baseline.
Largely replaced by computer-aided design software.
