private void RunScript(Guid id, ref object Outer, ref object Inner)
{
  var rhinoObject = RhinoDocument.Objects.FindId(id);
  if (rhinoObject is HatchObject)
  {
    var hatch = rhinoObject.Geometry as Hatch;
    Outer = hatch.Get3dCurves(true);
    Inner = hatch.Get3dCurves(false);
  }
}

import Rhino
rhino_object = Rhino.RhinoDoc.ActiveDoc.Objects.Find(id)
if type(rhino_object) is Rhino.DocObjects.HatchObject:
    hatch = rhino_object.Geometry
    Outer = hatch.Get3dCurves(True)
    Inner = hatch.Get3dCurves(False)
