Thanks a lot for the reply. Maybe I'm wrong but when I try for example
"pbwithin 3 of my edge selection" it gave me the indices within the same
sheet and not in it's periodic images. if I add bond for those atoms I get
a long bond from one edge to the opposite edge of the primary sheet..
May you guide me on that?
