Loft function not working

Hi,

I am trying to loft the red lines together to create a surface that matches the wave-like form in rhino, but the loft function isn’t working. Is someone able to please help me, i can’t figure out where i am going wrong. I have attached my current rhino + grasshopper script.

Thank you!


You need to attach your actual GH file with all Rhino data internalized (if there is any.) Using Nurbs curves made from points extracted from ISO curves can easily result in a Loft surface that does not match up with the original ISO curves. See if Interpolated curves work better.
