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 [out] | Double | Returns the curve length.

Examples

VBScript Example

    'This example will get the curve length of a spiral
    newscene
    dim length
    CreatePrim "Spiral", "NurbsCurve"
       GetCurveLength"Spiral", length
    logmessage "Curve length is: " & length
