I was watching this very interesting video showing some curviloft extension features.
And then I wonder how the loops of the following picture took from the video have been made.
I think I could do something like that drawing arcs and rotating or moving them.
This is what I got in some of my first tries, but it doesn’t look as perfect:
Any idea about how to make it look like in first picture?
I also found this interesting tutorial about how to draw a spiral but it’s a 2D one.
Thanks in advance.
