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.
