SelDup for closed curves and surfaces?

Is there any way to SelDup for closed curves and surfaces?

Hi @Giovanni_Romani
That can easily be done with a macro:

SelClosedCrv Invert Lock SelNone SelDup UnLock

and

SelSrf Invert Lock SelNone SelDup UnLock

HTH, Jakob

EDIT: Or did you mean combined? Then it’s:
SelClosedCrv SelSrf Invert Lock SelNone SelDup UnLock
