One time warning in boundary surfaces

Hi I tried creating a neighberhood inside an area of a curve with vorony streets and internal backyards.
it works, However the boundry surface has a runtime warning. rhino and grasshopper files attached

Check this:

  1. No need for the path, you can simply feed the curve into a srf component.
  2. This appears to be a planar voronoi. No need to use the 3D voronoi component.
  3. You can split the surface with the cell outlines.
  4. You can plug multiple values into the distance input. Use shift paths to have two curves per branch for the final surface creation…

PS: it’s called Voronoi and I internalised your input curve.

Thank you very much!
