I have been wondering for long time now and I haven’t find an answer myself, What global local view is used for?
For some time I thought that “Global/local view” option can be use to see and object like if it was a single scene, so no mater the rotation or scale that you can see it like if all transformation had been reset. But its not.
So there is a way to do that: there is a way to align views with and object?
Local view is simply an isolation mode for when you want to work on a specific piece of a model or scene, it doesn’t affect transformations or anything. It also reframe the camera position (I wish it wouldn’t do that btw).
About the second question, I don’t really understand what do you mean. Could you elaborate?
Select an object (or face, etc.), hold Shift and press “1” or “3” or “7” on the numpad. This will align the view to the local axis of the object or normals of the selected faces.
