## RemovePointFromPolygon

### Introduced

v1.5

### Description

Removes a point from the polygon being created.
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

    RemovePointFromPolygon( InputObj, [PointID], [PolygonID] );

### Parameters

Parameter | Type | Description
--- | --- | ---
InputObj | String | Mesh holding the polygon being built
PointID | Long | ID of the vertex to remove in the current polygon being built Default Value: 0
PolygonID | Integer | New ID of the polygon since it is being rebuilt from scratch (-1 is returned if polygon has now less than 3 points)

### Examples

#### VBScript Example

    ' Create a triangle

    dim obj, poly

    SIGetPrim "EmptyPolygonMesh", , , , obj

    SelectObj obj

    ApplyOp "CreatePolygon", obj, siUnspecified

    AddPointToNewPolygon obj, -2.229, 2.713, 0.000

    AddPointToNewPolygon obj, -3.140, -1.686, 0.000

    AddPointToNewPolygon obj, 1.744, -2.345, 0.000, , poly

    SelectObj obj & ".poly[" & poly & "]"
