Peeling layers
Use the Layers panel to set each system On, Faint or Off, or press Peel a layer to remove the outermost layer each time.
Looking closely
Select a part, then use Isolate (just that part), With skeleton (that part plus a faint skeleton) or Just this region. Hide removes a part; Show all brings everything back, and Undo (Ctrl/⌘+Z) steps back.
Sharing
Share copies a link (or opens your phone's share sheet) that reopens exactly what you are looking at: the angle, layers and card.
Saving an image
