Not being able to flow a geometry onto a surface to create a roof

Hi, I am having issues with flowalongsrf to create a roof around a cone surface.

1° issue is that the command doesnt seam with the geometry, leaving a open space when it shouldnt.
2° issue is that in the back of it the geometry that is flowingalongsrf is turning to be flat.

Please, need help. Thanks in advance.

Hello- it will be much easier to help if you provide a 3dm file with the objects you are working with.


super heavy due to the number of breps

Hello - just put some lines in or something - or the outline of the field of breps.
