Header file: MapBoundary.h.

The AcMapCircleBoundary represents a circle with a center point and a radius.

The AcMapCircleBoundary class is derived from the AcMapPointBoundary class. To get or set the circle’s center, use AcMapPointBoundary::GetPoint or AcMapPointBoundary::SetPoint function.

Do not subclass from this class.

You get an AcMapCircleBoundary pointer using the new operator, so you are responsible for deleting allocated memory with the delete operator.
