GetEndParameter Method

Returns the raw parameter value at the start or end of this curve.

Namespace: Autodesk.Revit.DB
Assembly: RevitAPI (in RevitAPI.dll) Version: 16.0.0.0 (16.0.0.0)
Since: 2014

Syntax

C# 
public double GetEndParameter(
	int index
)
Visual Basic 
Public Function GetEndParameter ( _
	index As Integer _
) As Double
Visual C++ 
public:
double GetEndParameter(
	int index
)

Parameters

index
Type: System Int32
0 for the start or 1 for end of the curve.

Return Value

The parameter.

Remarks

The start and end value of the parameter can be any value (as it is determined by the system based on the inputs). For curves with regular curvature like lines and arcs, the raw parameter can be used to measure along the curve in Revit's default units (feet). Raw parameters are also the only way to evaluate points along unbound curves.

Exceptions

Exception Condition
Autodesk.Revit.Exceptions ArgumentException curve is unbound and does not have start and end points. -or- index must be 0 for the start of the curve or 1 for the end.
Autodesk.Revit.Exceptions ArgumentNullException A non-optional argument was NULL
