Surface join

Hello all

I have question about, is there any special command to join 2 surfaces (similar like “connect crv” option)
Or how would you join those 2 surfaces ?

Please see attached file.

Thanks in advance

you can untrim the surfaces, extend them and split with each other to recover the edge between them. the surfaces are pretty messy to use a "quick "or “magic” solution.

Hello Diego

Thanks for reply.

I know they are messy because comes from digitizing data …
Unfortunately this is what I received from surveying crew.
I will need to play with this on earlier stage and do some amends before create surfaces.

Many thanks for solution
