 Syntax
 Syntax  The RebarShapeConstraintProjectedSegmentLength type exposes the following members.
 Constructors
 Constructors  | Name | Description | |
|---|---|---|
|   | RebarShapeConstraintProjectedSegmentLength | Constructs a new instance of a RebarConstraintProjectEdgedLength object using a shape parameter, direction, and reference types. | 
 Properties
 Properties  | Name | Description | |
|---|---|---|
|   | Direction | A vector specifying the direction of the constraint. The direction is fixed, and the shape is always constructed so that the segment direction has a positive dot product with this vector. | 
|   | IsValidObject | Specifies whether the .NET object represents a valid Revit entity. (Inherited from RebarShapeConstraint ) | 
|   | TripleProductSign | Sign of the z-coordinate of the cross product of the Direction property with the segment vector. TripleProductSign is 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. | 
 Methods
 Methods  | Name | Description | |
|---|---|---|
|   | Dispose | (Inherited from RebarShapeConstraint ) | 
|   | Equals | Determines whether the specified object is equal to the current object. (Inherited from Object ) | 
|   | GetHashCode | Serves as the default hash function. (Inherited from Object ) | 
|   | GetParamId | Return the Id of the parameter associated with this constraint. (Inherited from RebarShapeConstraint ) | 
|   | GetSegmentEndReferenceType | Choice of two possibilities for the start and end references of the length constraint. | 
|   | GetType | Gets the  Type  of the current instance. (Inherited from Object ) | 
|   | ToString | Returns a string that represents the current object. (Inherited from Object ) | 
 Remarks
 Remarks   The constraint has two references, indexed by 0 and 1, that do not have to correspond to the start and end of the segment. The constraint also specifies a direction as a 2D vector, which is not necessarily parallel to the segment, but must point from the segment's start toward its end.
