@Tomasz_Gniady  
have a look at the following script

[EdgeConnForMultipleSurfaces\_error\_replication\_SOLVED\_2.gh](https://femdesign.discourse.group/uploads/short-url/91j7eT1FDNLwqEteBJVlZwWs3pE.gh) (16.8 KB)

Can you just “setEdgeConnection” without creating a new one?

There is a Bug in constructing the surface again which changes the order of the edge
