Anyway you can see the basic idea how you can extract the generator curves by duplicating the edges and then flattening them.

Then you have some 2D curves that you can work on again with stuff like offsetting them.

Of course it is easier if the original generator curves were preserved, then you would not have to do that kind of extraction.
