the rotating view is too fast, no idea why I didn’t select anything different this time
It looks like you (or some module that you used) reconfigured your view animation settings. You can revert to defaults like this:
viewWidget = slicer.app.layoutManager().threeDWidget(0).viewWidget() viewWidget.animationIntervalMs = 5 viewWidget.spinIncrement = 2
These view properties are not stored persistently, so you another option to reset them is to save the scene, restart Slicer, and load the scene.
