Issue about numbering list in GH

Hallo Community,

a question about GH.

When I choose the surfaces from one Layer in Rhino and I set into a Brep, the component generate a numbering list for all the surface. Until this point everything is OK.

but if I close and open the same GH file and re-set the same surfaces, the Brep component generates a different numbering.

The numbering changes even if I internalize the surfaces.

there is a way to have always the same numbering??

Thanks in advance

Insert a Sort List component and it will be always the same, maybe use the are of the surface as sorting logic.
