Hello all,  
I am new in VTK please help me to resolve the following issue.  
I have volume data when i try to pass in vtkCutter function its give me the following error

volume = vtk.vtkVolume()  
volume.SetMapper(volumeMapper)  
volume.SetProperty(volumeProperty)

#create a plane to cut,here it cuts in the XZ direction (xz normal=(1,0,0);XY =(0,0,1),YZ =(0,1,0)  
plane=vtk.vtkPlane()  
plane.SetOrigin(10,0,0)  
plane.SetNormal(1,0,0)

#create cutter  
cutter=vtk.vtkCutter()  
cutter.SetCutFunction(plane)  
cutter.SetInputConnection(volume.GetOutputPort())  
cutter.Update()  
cutterMapper=vtk.vtkPolyDataMapper()  
cutterMapper.SetInputConnection( cutter.GetOutputPort())

#create plane actor  
planeActor=vtk.vtkActor()  
planeActor.GetProperty().SetColor(1.0,1,0)  
planeActor.GetProperty().SetLineWidth(2)  
planeActor.SetMapper(cutterMapper)

AttributeError :Traceback (most recent call last)

----\> 9 cutter.SetInputConnection(volume.GetOutputPort())  
10 cutter.Update()  
11 cutterMapper=vtk.vtkPolyDataMapper()

AttributeError: ‘vtkRenderingCorePython.vtkVolume’ object has no attribute ‘GetOutputPort’

…if you already have a volume object this should work:

```python
    #vol = vtkVolume()
    boxWidget = vtk.vtkBoxWidget()
    boxWidget.SetInteractor(vp.interactor)
    boxWidget.SetPlaceFactor(1.0)

    renderer.AddVolume(vol)
    interactor.Render()

    planes = vtk.vtkPlanes()
    def clipVolumeRender(obj, event):
        obj.GetPlanes(planes)
        vol.GetMapper().SetClippingPlanes(planes)

    boxWidget.SetInputData(vol.GetMapper().GetInput())
    boxWidget.OutlineCursorWiresOn()
    boxWidget.GetSelectedOutlineProperty().SetColor(1, 0, 1)
    boxWidget.GetOutlineProperty().SetColor(0.2, 0.2, 0.2)
    boxWidget.GetOutlineProperty().SetOpacity(0.7)
    boxWidget.SetPlaceFactor(1.0)
    boxWidget.PlaceWidget()
    boxWidget.InsideOutOn()
    boxWidget.AddObserver("InteractionEvent", clipVolumeRender)

    renderer.ResetCamera()
    boxWidget.On()
    interactor.Start()

```

Thank you for your reply, definately i will try this.  
But basically i am looking for the cutter function which cuts the 3d volume dicom image,  
which is exactly done in ITK-SNAP.

When i used vtkplotter.addons.addCutterTool( volume ) it gives me following error :
