A drawing created using a compass and straight edge is called a construction.See http://en.wikipedia.org/wiki/Compass_and_straightedge_constructions
A compass is mainly used to draw perfect circles, but it can also be used to draw arcs of different sizes.

Instruments; the types used to make a manual drawing. Firstly a drawing board is needed to draw the drawing, so it is at a angle making it easier (However some people don't like it but it does improve the drawing). A engineering set square is needed to draw lines at a angle. A protractor is used to measure angles. A typical protractor is a semi-circular piece of plastic with 180 degrees printed around its curve. This piece of equipment is not only used in graphics for constructing accurate drawings but is also used in subjects like Mathematics. A compass is an absolute essential piece of equipment. It is well worth buying a good set which includes at least two compasses allowing the drawing of small and large circles. The drawing opposite is a 'bow' compass, this is used for drawing small circles very accurately. Cheap compasses tend to slip on the paper and break quite easily. A good, quality compass set will last a life time. Drawing Pencils are a basic requirement of any graphics course. You need a number ranging from 2B to 2H. These letters refer to the hardness of the pencil lead. When sketching a soft lead such as 2B is can be used to produce quick drawings and shading. On the other hand , when drawing precisely a 2H or even a harder pencil such as a 4H is ideal. This type of pencil keeps its sharp edge for longer and produces very fine lines.

A compass perhaps?
For navigation, it shows you what direction you are facing. In drawing, it is a device for drawing circles.
There are several different types of compass:magnetic compass, uses a light weight bar magnet on a pivotgyroscopic compass, uses a gyroscope (either mechanical or LASER ring)drawing compass, used to assist in drawing circles for drafting or artetc.

Beam Compass.
Geometrical compass To draw a perfect circle, and another compass for determining directions
A construction. A contruction is a geometric drawing of a figure usually made by a compass and a straightedge.
