Indicates if this arc is a portion of the boundary of a 2D circle. An elliptic arc is circular if the ellipse upon which it is based is a circle, meaning the lengths of its major and minor axes are equal.
Use EllipticArcSegment.createCircularEllipticArc(Point, Double, Double, Double, SpatialReference) and EllipticArcSegment.createCircularEllipticArc(Point, Point, Point, SpatialReference) to create circular arcs.
