## CustomProperty.AddFCurveParameter

### Introduced

v4.0

### Description

Adds an FCurve Parameter to the CustomProperty. An FCurve of this type is often called a "Profile Curve" because, unlike most FCurves, this curve does not animate any parameter, but instead is available for use in any fashion the plug-in developer or user wishes. Unlike parameters that have simple types like an Integer or a String, this Parameter is an instance of an FCurve. It uses units of Frames for its x axis, but because it does not directly animate any object this axis can actually be interpreted in any fashion. An example use of an FCurve parameter can be found on the Bulge Operator.
The FCurve object is retrived via the Parameter.Value property. This should not be confused with the method for retrieving an FCurve that is animating a "basic" parameter, via the Parameter.Source property.
In order to view the FCurve on the Property Page for the custom property use PPGLayout.AddFCurve.

### C# Syntax

    Parameter CustomProperty.AddFCurveParameter( String in_ScriptName );

### Scripting Syntax

    oReturn = CustomProperty.AddFCurveParameter( ScriptName );

### Return Value

The newly created Parameter object.

### Parameters

Parameter | Type | Description
--- | --- | ---
ScriptName | string | Script name of the new parameter
