There are three types of circles. Circles around a point M and through a point A, circles around a point M with radius AB, and fixed circles. Each type has an own tool. The first kind expects two points, the second three, and the last only one.

Drawing a circle can be restricted between two defining points, yielding circular arcs. In this case, it is possible to keep the arc less than 180 degrees (i.e., always the shorter arc will be drawn connecting the ends of the arc). You select the end points using a button in the property dialogs of the circle.

Circles can be filled. Arcs can be filled in two ways, either as a chord section of a circle, or as a pie.

Circles can be restricted to their necessary parts. These partial circles are only drawn in little arcs through all points related to them.
