Uses for Drafting Compasses, Dividers, & Sets

A compass has two arms one containing a needle (shoulder needle) and the other a graphite lead. To draw a circle and arc with the compass adjust the width/spread (distance between needle point and lead); place the needle point at the center where the two center lines intersect; rotate the compass by twisting the thumb and forefinger to produce the circles line. It is important to sharpen the lead to a chisel point to produce lines of even thickness while rotating the compass. Generally soft lead (F or HB) are used in compasses so the circle are drawn as dark object lines.

A dividerís two arms have a point which ends touch when closed. To compare sizes of drawing elements open the divider points across one element then compare against the second or compare by measuring each against a scale ruler. Measure distance by opening the divider points to a set scale then plot across the drawing or map to get a distance. A divider is also used to divide a line into segments.

Drafting sets include both a divider and compass plus some have additional tools for inking and lettering.
