Merge surfaces to cut-out panels that do not lie on top of each other

Hello everyone,

I’m trying to get out all of the panels for manufacturing. But because I have 2 faces of brep, my panels are divided 2 times. causing that I have 2 times the same numbers, and because of which 2 panels will probably(?) be placed on top of each other as can be seen on the top left of the picture. How can I join these properly? If I use brep join, there are still 2 surfaces.

I think you’ll have to internalize these curves in your GH file
