Hello - it looks like Untrim is what you need here but also your object looks to be split up into multiple faces that might be unnecessary - can you post a file with that object?

-Pascal

i tried with untrim but it didnt work. When i was workin with a surface without thickness, the command untrim used to be efficient, but now, as i transformed the red surface so it get thickness, the untrim command doesnt work
I dont know why but i cant upload the file:(

Hello - Export the object to a new file and add it to your post using the ‘upload’ icon:

-Pascal


Yes, i know how to do it, i meant it doesnt work when i try to do it

Hm - is the file huge?

Hello- it is a bit tedious, but ExtractSrf the inner and outer surfaces, Untrim the top edges there, retrim with a horizontal plane and retrim any other edges as needed with the details lower down in the object anmd then join it all up again. The top can then be closed with Cap.
