   public void AddConstraintParallelToSegment(
	int iSegment,
	ElementId paramId,
	bool measureToOutsideOfBend0,
	bool measureToOutsideOfBend1
)Parameters
- iSegment Int32
- Index of the segment (0 to NumberOfSegments - 1).
- paramId ElementId
- Id of a parameter to drive the constraint. To obtain the id of a shared parameter, call RebarShape.GetElementIdForExternalDefinition().
- measureToOutsideOfBend0 Boolean
- Choose between two possibilities for the first reference of the length dimension. If false, the reference is at the point where the bend begins; equivalently, at the projection of the bend centerpoint onto the segment. If true, the reference is moved outward by a distance equal to the bend radius plus the bar diameter; if the bend is a right angle or greater, this is equivalent to putting the reference at the outer face of the bend.
- measureToOutsideOfBend1 Boolean
- Choose between two possibilities for the second reference of the length dimension.
