Hi I’m new to slicer development and I wanted to update my code to the 4.10 version. I just had a question of how to enable the “edit in 3D view” section using the qMRMLSegmentEditorWidget?

I got to this point:  
self.segmentEditorWidget.setActiveEffectByName(“Erase”)  
effect = self.segmentEditorWidget.activeEffect()  
effect.setParameter(“Editin3DViews”,“1”)  
effect.self().onApply()  
But whenever I attempt to erase, it will only rotate/displace the volume.

Thanks

Parameter names are case sensitive (`EditIn3DViews` is correct, `Editin3DViews` is incorrect). Also, this parameter is shared between paint and erase effects, therefore you need to set it using `setCommonParameter`.

So, you need to change

```
effect.setParameter("Editin3DViews","1")

```

to

```
effect.setCommonParameter("EditIn3DViews","1")
```

Sorry about that, will keep that in mind for next time
