Hi all

Like figure, I would like to pop up 2D slices view on only one 3D view when using the multi 3D view

 ![sdsd](https://us1.discourse-cdn.com/flex002/uploads/slicer/original/3X/d/7/d7662e0774a0a59ba18021d13493e4ceb0aec5e9.png)

What is the easiest way to implement this ?

Thanks

> Hi developers, I have a problem switching on the slice views on or off in the 3D view from Python permanently. The code I am using for i.e. switch on the red slice view is: current\_slice\_node = slicer.mrmlScene.GetNodeByID(‘vtkMRMLModelDisplayNode1’) current\_slice\_node.VisibilityOn() This code works well until one changes the position of the slice by i.e. scrolling in the slice view. I guess since the “eye” in the slice view is still “closed” the update will set the visibility again to 0 and…
