Build a drafting combination

A registered straight line, plus the angles you use

A T-square establishes the board-edge reference. A triangle rests against its blade to guide perpendiculars and the triangle’s stated angles. Add the second geometry only if your drawing calls for it.

Includes the selected rulers, supplied individually. Add your own drawing board, paper and pencil.
