If you are switching the eye on/off then that is just like a layer - the components are still there just hidden for editing purposed.
This is the same as the curtain wall if you have ever used it.
Some components will allow you to set an 'invisible' type so it is there but can't be seen.
Others allow you to add and delete in the preview panel.
