I have created several 3dwidgets,and now I need to get ThreeDWidget.  
I can’t get ThreeDWidget in order.  
I get the name of ThreeDWidget first.The name doesn’t correspond to the ID.  
But when I try to get qMRMLThreeDWidget through names,it has no return value.

@f1oNae, have you tried with some of the snippets in the python script repository ([Script repository — 3D Slicer documentation](https://slicer.readthedocs.io/en/latest/developer_guide/script_repository.html))? More precisely, the snippets in this section may help you: [Access VTK rendering classes](https://slicer.readthedocs.io/en/latest/developer_guide/script_repository.html#access-vtk-rendering-classes).

Let us know if this does not help you.

yeah,I Iterate through all 3D views in current layout,finally find that the real name of the 3DWidget is “View1”-“View16” instead of “ThreeDWidgetX”!!!  
Thanks for your help!
