A drafting machine improves the speed of manual drafting by consolidating multiple essential tools into a single, integrated instrument. By combining the functions of a T square, triangle, protractor, and scale, it eliminates the need to constantly switch between separate devices.12

Furthermore, the machine allows a straightedge to be moved across the drawing board while maintaining any desired angle relative to the board's edge. This capability streamlines the drafting process, significantly increasing the efficiency and speed with which technical drawings can be produced compared to traditional manual methods.2
