---Purpose: Constructs the sensitive arc object defined by the
-- owner OwnerId, the circle Circle, the parameters u1
-- and u2, the Boolean FilledCircle and the number of points NbOfPoints.
-- u1 and u2 define the first and last points of the arc on Circle.

---Purpose: Constructs the sensitive circle object defined by the
-- owner OwnerId, the array of triangles apolyg3d, and the Boolean FilledCircle.
-- apolyg3d is an array of consecutive triangles on the
-- circle. The triangle i+1 lies on the intersection of the
-- tangents to the circle of i and i+2.
