Hello !  
I am trying to dispaly a segmentation in the 3D view using the python interactor but i cant find the command to activate/deactivate the equivalent of “show 3D” in segmentation Editor.  
 ![image](https://us1.discourse-cdn.com/flex002/uploads/slicer/original/3X/7/c/7c935f837363f9b230e611d6ad352fadea7905a7.png)

for now i’ve tried :  
segmentation = slicer.util.getNode(‘TC4\_RH\_ctg\_mask.nii.gz’)  
segmentationDisplayNode = segmentation.GetDisplayNode()  
segmentationDisplayNode.SetSliceIntersectionVisibility(True)  
segmentationDisplayNode.SetVisibility(True)

but it does not change the 3d display of the segment.  
Thanks in advance 🙂

Nicolas

The missing ingredient is `CreateClosedSurfaceRepresentation()`

Hi,

This is not working in version 5.4.0 because of:

`'vtkSegmentationCorePython.vtkSegmentation' object has no attribute 'GetDisplayNode'`

How can I do it in this version?

Thanks.

`GetDisplayNode` is for `vtkMRMLSegmentationNode` (as returned by `getNode`) not `vtkSegmentation`. There are several layers, but they make sense to keep the methods localized by dependencies (`vtkSegmentation` doesn’t know about `MRML` so it can be used more generally in the future).
