I have attached my script below:
GrevillePoints.gh (5.4 KB)

I am quite puzzled with the two greville points outside of the curve. I wonder what caused this erroneous output?

Hi @Wiley,

If you want the same outpoint as EditPtOn, then pass a false to GrevillePoints.

public Point3d[] RecalculateGrevilleMatrix(Curve curve)
{
  if (null != curve)
  {
    var nurb = curve.ToNurbsCurve();
    if (null != nurb)
      return nurb.GrevillePoints(false).ToArray();
  }
  return new Point3d[0];
}

just for the sake of satisfying my curiosity, what are those two points outside of the curve?
