## SIAddPointOnCurveAtStart

### Description

Adds a point at the start of a curve.

### Scripting Syntax

    SIAddPointOnCurveAtStart( InputObj, [X], [Y], [Z], [Local], [CurveType], [PreserveTrace] );

### Parameters

Parameter | Type | Description
--- | --- | ---
InputObj | String | Curve to set points on.
X | Double | X coordinate Default Value: 0
Y | Double | Y coordinate Default Value: 0
Z | Double | Z coordinate Default Value: 0
Local | Boolean | True if points are in local coordinates, False if they are in global coordinates. Default Value: False
CurveType | Integer | Type of curve Default Value: -1
PreserveTrace | Boolean | True if the current trace of the curve should remain intact with the addition of the new point. Default Value: False

### Examples

#### VBScript Example

    'This example shows how to add points before the start of a curve
    newscene
    'Create a curve and add points at start.
    'Adding points at start will create a curve that
    'has the same trace as adding the same points at end
    'but with start and end points reversed.
