This black-and-white technical illustration depicts a traditional T-square used in manual drafting, featuring a perpendicular head with four screw holes for attachment to a drawing board and a long, straight blade ending in a circular hole for hanging or alignment. The design emphasizes rigidity and accuracy, allowing users to draw horizontal lines and guide triangles for vertical or angled lines. Commonly made of aluminum or wood with metal reinforcements, it remains a foundational tool in architecture, engineering, and technical illustration education.

Used on architecture/engineering educational sites, drafting supply stores, museum archives of design tools, or historical tool collections; matches user intent for learning about manual drafting equipment, purchasing vintage drafting tools, or illustrating technical drawing workflows.
