Get the percentage of the curve length at a given knot.
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#).

InputObj | String | Curve to evaluate. |
Index | Integer | Knot index. Knots are indexed starting at 0. |
Percentage | Double | Returns the percentage of the curve length at the given knot. |
