Well, that's a good example of the kind of thing that would be quite difficult to do without flow and twist...

I suppose it would be a matter of constructing the proper path curves and then doing a sweep around those, but it would really require a lot of effort to manually draw the curves for those paths, as compared to using the new flow & twist commands to make them. That's why making those new commands has been a priority for v3 so far, since they really simplify certain kinds of constructions like that example.

Without flow and twist the next best thing would probably be a script that would generate the paths from some program code.
