Thanks for the answers, but I still have doubts. I need the hexagonal structure with circles that I drew, with the proportion that I created. Before you send me the file I tried with a helmet without subD , but with mesh thinking I have more linear polygonal structures and I modified the structure to obtain a symmetric helmet (photo); now i’m trying to change what you sent me trying to insert the structure I want, but nothing.
I don’t understand what you mean when you say ‘helmet surface is not rectangular like your planar representation’ … I intended the ‘sporph’ command as a command that adapts the structure to the surface where you want to insert it; for example, in the link that I put in the first message about another discussion, the structure was a hexagonal grid on a curved surface given by the revolution of an ellipse … even there there was no correspondence between target surface and box. I don’t know if I’m saying correctly
