This black-and-white illustration shows a person’s hands using a T-square and pencil on a tilted drafting board, emphasizing precision and control in traditional technical drawing. The setup includes a parallel ruler clamped to the board edge, ensuring accurate horizontal lines, while faint grid lines suggest underlying layout planning. Such methods were foundational in pre-digital design workflows across engineering and architecture fields.
