2. "SHIFT" all divided points and connect them to get the nest pattern and use ''Move'' function to make more layers (or duplicate series of same script group to increase the thickness of object) if needed.
3. Simply use "Pipe" tool to manipulate a 3D object.
The first experiment I took is based on "CrossRef" function which can duplicate points logically. Meanwhile, using a external point as a reference point to create gradual change.
And I also understand the use of "Loft" fuction.
