Constrain the length of a segment by parameterizing its length.

Namespace: Autodesk.Revit.DB.Structure
Assembly: RevitAPI (in RevitAPI.dll) Version: 22.0.0.0 (22.1.0.0)

Syntax

C#
`public void AddConstraintParallelToSegment( int iSegment, ElementId paramId, bool measureToOutsideOfBend0, bool measureToOutsideOfBend1 )`

Visual Basic
`Public Sub AddConstraintParallelToSegment ( _ iSegment As Integer, _ paramId As ElementId, _ measureToOutsideOfBend0 As Boolean, _ measureToOutsideOfBend1 As Boolean _ )`

Visual C++
`public: void AddConstraintParallelToSegment( int iSegment, ElementId^ paramId, bool measureToOutsideOfBend0, bool measureToOutsideOfBend1 )`

iSegment: Type: System Int32
Index of the segment (0 to NumberOfSegments - 1).

paramId: Type: Autodesk.Revit.DB ElementId
Id of a parameter to drive the constraint. To obtain the id of a shared parameter, call RebarShape.GetElementIdForExternalDefinition().

measureToOutsideOfBend0: Type: System 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: Type: System Boolean
Choose between two possibilities for the second reference of the length dimension.

Exceptions

Exception	Condition
Autodesk.Revit.Exceptions ArgumentException	iSegment is not between 0 and NumberOfSegments. -or- paramId is not the id of a shared parameter in the current document, or its unit type is not UT_Reinforcement_Length or UT_Angle.
Autodesk.Revit.Exceptions ArgumentNullException	A non-optional argument was null
