The term polydrafter was coined by Ed Pegg Jr., who also proposed as a puzzle the task of fitting the 14 tridrafters—all possible clusters of three drafters—into a trapezoid whose sides are 2, 3, 5, and 3 times the length of the hypotenuse of a drafter.
The drafter uses several technical drawing tools to draw curves and circles. Primary among these are the compasses, used for drawing arcs and circles, and the French curve, for drawing curves. A spline is a rubber coated articulated metal that can be manually bent to most curves.

As a necessary means for visually conveying ideas, technical drawing has been in one form or another a part of human history since antiquity. The use of these early drawings was to express architectural and engineering concepts for large cultural structures: the temples, monuments, and public infrastructure.
