circle
Makes a circle given a center and radius. The circle is a truly a polygon made
of several line segments. The number of segments used is effected by a field
within the circle object called "circleEdges". This fields is by default referenced
to a global field of the same name, so that changing the global will effect all
referenced circles. To change the circleEdges count of one circle independently
just dereference the field with the circle. The circle will be embedded in the
current drawing plane. To make it in a different plane change the drawing plane
and draw the circle there. Like all objects the the circles fields may be changed
any time by accessing them through the database, double clicking on the circle,
pulling up the context menu, etc. It is not necessary to delete the circle and
start over if you get the radius wrong, although this can be done if it is easier.
