< the basic idea how you can extract the generator curves by duplicating the edges and then flattening them.
That's the trick!
Does it possible to imagine that as a script of a commun function? As an "extract generator" or it's trivial as just the box frame can do the job?
But I must make the modification now for see if all that works :)
Because the flat curves must will be curvated again!
