Hi @anon39580149,

It’s a control point mismatch and the ruled surface wants the control points to align per count I believe.

Bottom control points (count/position as expected):

Top control points (extra near curve seam):

Recreating/rebuilding your top circle should fix it up just fine.

Hope that helps, cheers!

But still weird because Grasshopper recognize the shape as surface.

And this fix the output surface to bake it as surface:

Rhino.Geometry.Surface.CreatePeriodicSurface

 private void RunScript(Brep brep, bool bake, bool SplitKinkyFaces)
  {
    if (!bake) return;
    var id = RhinoDocument.Objects.AddBrep(brep);
    bool sp = false;
    if (SplitKinkyFaces)
      sp = true;
    RhinoDocument.Objects.Replace(id, brep, sp);
