Converting SubD to Nurbs

Grasshopper
1

Is there a grasshopper plugin that allows the conversion to Nurbs within Grasshopper?
Thank you.

You might want to assign your post to the Grasshopper category so more Grasshoppers see it.

For a simple conversion you can plug a SubD into a Brep component. For a quad sphere, you get 24 surfaces. I also attached a Grasshopper definition with a simple c# script which has the packed option. That creates just two surfaces for a quad sphere…

private void RunScript(SubD SubD, ref object brep)
  {
    brep = SubD.ToBrep(SubDToBrepOptions.DefaultPacked);
  }
