The surface created from sweep is loose
the sweep surface is taking in count the continuity while the patch doesn’t. If you set the sweep continuity to position instead of tangency or curvature it will work more similar to the Patch:
you can use BlendCrv with the Edges option to add more cross sections to have more control:

Thank you for helping me, You give me the rhino file you create the surface!
May I ask you ? if I learn to use grasshopper, Can I take this surface?
as I said above and Pascal suggested the same in other of your posts. spend time in tutorials, manuals, etc. there is no shortcut
having someone else files doesn’t help too much if you don’t understand the process underneath

Hello - the great advantage of building simple surfaces is that it is easy to move points if there is something yo do not like.
