What drafting tool is used to draw arcs and circles?

The compass is specifically designed to draw arcs and circles, making it the correct choice for this question. It consists of two arms, one with a pointed end that serves as a pivot point, and the other with a pencil or marking tool. By placing the pointed end at the desired center of the circle or arc and rotating the pencil end around it, you create a perfect curve.

Dividers, while similar in appearance, are primarily used for measuring distances on a drawing or for transferring measurements rather than specifically for drawing circles or arcs. They have pointed ends that allow for strikes but do not have the capability to draw curved shapes as the compass does.

Circle makers and trammel points can also create circular or arc shapes, but they are not as universally used or versatile as the compass for simple circle drawing. Circle makers may refer to a specialized tool that creates perfect circles, whereas trammel points are typically employed for larger arcs and circles and involve a more complex setup, which can be cumbersome for quick drawings.

Thus, the compass remains the most practical and widely used tool for drawing arcs and circles in drafting.
