Description
Constructs a CircularArc given the From Point, the Bearing Angle, the desired orientation, the desired Chord Distance, and the desired CircularArc Length. The Bearing Angle is measured in radians. The Chord Distance must be less than the Arc Distance, otherwise an error is returned.
Remarks
-isCCW stands for "is counter clockwise"
