Circular arcs

Circular arcs can be entered by clicking three points on the arc or by clicking the center of the supporting circle as well as the begin and end vertex of the arc. They can be filled in Postscript fashion, and can have arrows.

A common application for arcs is to mark angles in drawings. The snap keys are useful to create such arcs: set arc creation to center & 2 pts, select snap to vertex and snap to boundary, click first on the center point of the angle (which is magnetic) and click then on the two bounding lines.
