## X3DObject.GetActivePrimitive2

### Introduced

v9.0 (2011)

### Description

Returns the 3D object's active Primitive for a given frame.
Note: Although the scene root is a kind of Model it does not support primitives. In this case this function will return Nothing.
This method has the added convenienence of allowing sequential evaluation of simulation objects without risking a simulation restart because the scene time and given time don't match.
Note: This method could return an invalid object in python, use X3DObject.GetActivePrimitive3 instead.

### C# Syntax

    Primitive X3DObject.GetActivePrimitive2( Object in_Frame );

### Scripting Syntax

    oReturn = X3DObject.GetActivePrimitive2( [Time] );

### Return Value

Primitive

### Parameters

Parameter | Type | Description
--- | --- | ---
Time | Double | Time (in frames) at which to get the primitive Default Value: Current time in frames

### Examples

#### Python Example

    #

    #	This example illustrates how to get the active primitive object from an

    #	X3DObject object and how to detect if the object supports primitives.

    #

    from win32com.client import constants

    Application.NewScene( None, False )

    cube = Application.ActiveSceneRoot.AddGeometry( "Cube", "MeshSurface" )

    twist = Application.ApplyOp("Twist", cube, 3, "siPersistentOperation", None, 0)[ 0 ]

    twist.angle.AddFcurve( None, constants.siLinearInterpolation, None, [ 1.0, 0.0, 10.0, 180.0 ] )

    Application.LogMessage( cube.ActivePrimitive.Geometry.Points[ 5 ].Position.Y )

    Application.LogMessage( cube.GetActivePrimitive2(5).Geometry.Points[ 5 ].Position.Y )
