RebarShapeDefinitionBySegmentsAddListeningDimensionSegmentToBend Method

Specify a dimension perpendicular to one fixed-direction segment, referring to that segment and some other bend in the shape, measured by a read-only parameter.

Namespace: Autodesk.Revit.DB.Structure
Assembly: RevitAPI (in RevitAPI.dll) Version: 26.0.4.0 (26.0.4.0)

Syntax

C++

public void AddListeningDimensionSegmentToBend(
	ElementId paramId,
	double constraintDirCoordX,
	double constraintDirCoordY,
	int iSegment0,
	int iSegment1,
	int iEnd1
)

Public Sub AddListeningDimensionSegmentToBend ( 
	paramId As ElementId,
	constraintDirCoordX As Double,
	constraintDirCoordY As Double,
	iSegment0 As Integer,
	iSegment1 As Integer,
	iEnd1 As Integer
)

public:
void AddListeningDimensionSegmentToBend(
	ElementId^ paramId, 
	double constraintDirCoordX, 
	double constraintDirCoordY, 
	int iSegment0, 
	int iSegment1, 
	int iEnd1
)

member AddListeningDimensionSegmentToBend : 
        paramId : ElementId * 
        constraintDirCoordX : float * 
        constraintDirCoordY : float * 
        iSegment0 : int * 
        iSegment1 : int * 
        iEnd1 : int -> unit

Parameters

paramId ElementId: Id of a parameter to report the length of the dimension. The parameter will be read-only on Rebar instances.
constraintDirCoordX Double: The x-coordinate of a 2D vector specifying the constraint direction.
constraintDirCoordY Double: The y-coordinate of a 2D vector specifying the constraint direction.
iSegment0 Int32: Index of the first segment (0 to NumberOfSegments - 1).
iSegment1 Int32: Index of the second segment (0 to NumberOfSegments - 1).
iEnd1 Int32: End (0 or 1) of the second segment.

Exceptions
