Drafting dividers are tools for comparing sizes, dividing line segments, and measuring distances on drawings used by draftsman, artist, and other craftsman. Dividers are also popular in the maritime industries for plotting navigation using scaled nautical maps and charts.
The terms
compass
and
divider
are often interchanged, for each instrument can be used to draw
circles
, mark divisions (divide a given distance), or simply mark a distance. Technically, a compass is a
drafting
instrument that has one
pen
or
pencil
point and one sharp point that is positioned at the centre of the circle to be described, while a
divider
, on the other hand, has two sharp points, one for the centre and the other for scribing or marking.
Caliper
is a corruption of
calibre
, the diameter of a hole (as in a firearm) or of a cylindrical or spherical body. The outside caliper has inwardly curved legs that measure the diameters of solids created by rotating tools, such as lathe-turned objects, and the inside caliper has outwardly curved legs for measuring bores.
