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 …
If anyone knows why it would really help me ! 
Thank you in advance !
if you need help share your file
Oh yes of course I forgot to share it sorry …

Thank you very much ! 
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 ? 
You created a polyline from lines and the result was brep not surface
I get It ! Thank you !
