Thank you all for the help!
The problem was solved by exploding the polysurface and joining the surfaces several times.
Hi Elsa - to clean up non-manifolds, ShowEdges > NonManifold and zoom to these edges - a non-manifold edge is where more than two faces share an edge - you will often be able to see where (in wireframe or ghosted display modes) there is an internal face in what otherwise may be a solid, or a 'fin surface sticking into space - you can ExtractSrf and delete these faces.

Dear all, I have a ship hull with no deck. So I created the deck using plane at the midship > extrude to fill the entire deck > join > mergeallsurface … but Im still seeing that there is an open polysurface in the properties window

s. Could anyone assist on how I could close the model surface?

Hello @nachetz , thank you for the file, as I am using rhino 7, I am unable to open a rhino8 version, could I know the steps you took? Thank you
The problem is not the deck. The hull contains a “bad” surface.
SelBadObjects shows the entire hull and deck as a bad object.
ExtractBadSrf extracts the bad surface and leaves it selected.
Delete the bad surface.The model remains an open surface.
ExtractSrf one of the surfaces adjacent to where the bad surface was.Join the extracted surface and the remainder of the polysurface.The hull and deck should be a single closed polysurface.

I have the same problem with this file, can anyone help me close the polysurface ?
where did this model come from? it’s pretty messy, was it imported from another package?
it’s also modeled in Millimeter with a tolerance of .001 which is reeeally tight. Does it need to be that tight?
what is the desired output? Are you 3d printing it? Cnc machining? rendering?
