Hi,

I am not sure what is the best way to export a segmentation to a predefined empty vtkMRMLModelNode?  
Assume that I have a vtkMRMLModelNode named “Model”.  
I currently use the following

> shNode = slicer.mrmlScene.GetSubjectHierarchyNode()  
> exportFolderItemId = shNode.CreateFolderItem(shNode.GetSceneItemID(), “Segments”)  
> slicer.modules.segmentations.logic().ExportAllSegmentsToModels(outSegmentation, exportFolderItemId)

but I want to export directly to the node = slicer.util.getNode(“Model”)  
Is it possible?

Thanks

You can set vtkPolyData from a segmentation node as shown in these [examples in the script repository](https://www.slicer.org/wiki/Documentation/Nightly/ScriptRepository#Get_a_representation_of_a_segment).
