A drafting machine is a specialized instrument designed to streamline the creation of engineering drawings by integrating several essential tools into a single unit.1

It combines the functions of the following equipment:

T square: Used for drawing horizontal lines.
Triangle: Used for drawing vertical and angled lines.
Protractor: Used for measuring and setting specific angles.
Scale: Used for measuring distances and maintaining accurate proportions.

By allowing a straightedge to be moved across the drawing board while maintaining any desired angle, the drafting machine significantly increases the efficiency and speed of the drafting process.2
