L'operazione close layout non è annullabile

Oggi ho richiamato il comando “close” mentre ero nel layout per chiudere una polylinea, e invece che chiudere la curva mi ha chiuso il layour… e l’operazione non è annullabile, 2 ore di lavoro buttate, vorrei segnalare il problema perchè l’ho trovato davvero noioso.
un saluto, Riccardo

Hi @riccardo.foschi2
There is no native Close command in Rhino, I think. There’s CloseCrv, which I’m guessing you are refering to, but that shouldn’t do anything to your layout. Then there’s CloseViewport, and if you’ve called that command INSTEAD of CloseCrv, it should still give you a dialog box that you need to actively confirm before it closes/deletes the layout. Do you not see the dialog box if you run CloseViewport while in layout?

Yes that’s it, thanks for your answer.
I usually just type “Close” to recall “CloseCrv” but I probably selected “CloseViewport” instead, I didn’t see the warning dialog box, maybe I pressed enter twice too fast?

Anyway, the problem is not the shortcut or the command that I’ve used to close it, but it’s the fact that the layout erasing can’t be undone.
