When we look at, from a certain point of view we have element that are hidden
The idea, each parts being locate in the front of the select part(s) will be hidden. This will clear the view between the user and the select part(s) from unwanted elements, to see the select part in their context.
If we want to remove some other part, we simply pivot the view by few degree and run the command again to remove some extra parts from the view.
