Accidentaly pressed a similar smooth button

[Anonymous]

Hi all,

I've a problem, I've accidentaly pressed some hotkeys when I was modeling a poligonal object and now I see a NURBS similar with my poligon object like a cage around it. I've tryed to go back with history but nothing, it undo my changes on object but no to previus object view. How I can back or disabilitate this view?

1 key is normal view 2 key is smoth object with hull cage and 3 is normal smooth mesh preview ... Try pressing 1 again
