I can't slice extruded surface

Hello,
I’m facing a small problem and I can’t figure out why it’s happening … I created a surface out of a catenary.with extrusion. Now I want to slice this surface with curves. The curves seems okay but the the surface doesn’t work with the SrfSplit block …

I’m not sure I understand what is causing the problem in the first place …
I get it that it is because of the catenary but why ? :sweat_smile:
