GE_DLLEXPIMPORT Adesk::Boolean overlapDirection() const;
Description
Returns true if the two curves are oriented in the same direction where they overlap and 0 if they are oriented in the opposite direction.
Before determining overlap direction, check that overlaps exist with AcGeCurveCurveInt2d::overlapCount. If there are no overlaps between the two curves and this function is called, it returns 1, which is a meaningless value in this instance.
