Rebar   |  
 Constructs a new instance of a RebarConstraintProjectEdgedLength object using a shape parameter, direction, and reference types. 
 Namespace: Autodesk.Revit.DB.Structure
Assembly: RevitAPI (in RevitAPI.dll) Version: 25.0.0.0 (25.0.0.0)
public RebarShapeConstraintProjectedSegmentLength(
	ElementId paramId,
	UV direction,
	int tripleProductSign,
	RebarShapeSegmentEndReferenceType refType0,
	RebarShapeSegmentEndReferenceType refType1
) Parameters
- paramId ElementId
 - The Id of a Rebar Shape parameter.
 - direction UV
 - A vector specifying the direction of the constraint. The direction is fixed, and the shape is always constructed so that the segment's direction has a positive dot product with this vector.
 - tripleProductSign Int32
 - Sign of the z-coordinate of the cross product of the "direction" argument with the segment vector. In other words, 1 if the segment direction is to be on the left of the constraint direction, or -1 if the segment direction is to be on the right.
 - refType0 RebarShapeSegmentEndReferenceType
 - Choose between two possibilities for the first reference of the length constraint.
 - refType1 RebarShapeSegmentEndReferenceType
 - Choose between two possibilities for the second reference of the length constraint.
 
| Exception | Condition | 
|---|---|
| ArgumentException | paramId is not a valid Element identifier. -or- tripleProductSign is not 1 or -1. | 
| ArgumentNullException | A non-optional argument was null | 
| ArgumentOutOfRangeException | direction has zero length. -or- A value passed for an enumeration argument is not a member of that enumeration |
