Cull Shuttered Elements

Hello everybody,

I have a problem culling my shattered elements after an offset.

In my case I try to create an offset of my helicoidal structure, but after a specific value the curves will overlap. Then I want to delete the overlapping part of the curves so that later on I am able to loft between all of them again. But I don't get it.

Maybe you can help me again?

Thanks a lot.

Greetings

Phil
