## GetCurveLength

### Description

Gets the length of a nurbs curve.
Note: This command uses output arguments. C# and some scripting languages (such as JScript, PerlScript and Python) don't support arguments passed by reference so you need to use the best workaround for your situation:
For scripting languages this command returns an ISIVTCollection which you can use to get the output arguments.
For C# you can use the XSIApplication.ExecuteCommand method to call this command. ExecuteCommand packs the output arguments into a C# System.Object containing an Array of the output arguments (see Calling Commands from C#).

### Scripting Syntax

    GetCurveLength( InputObj, [Length] );

### Parameters

Parameter | Type | Description
--- | --- | ---
InputObj | String | Curve to evaluate.
Length | Double | Returns the curve length.

### Examples

#### VBScript Example
