Region intersecting two trees

I want to region-intersect two trees each carrying a bunch of closed polygons. List “A” (red curves) has e.g. 4 items, list “B” (blue curves) has different polygons but the same amount as list A. How can I region intersect each index across the two trees? E.g. index 0 (List A) with index 0 (List B), index 1 (List A) with index 1 (List B), index 2 (List A) with index 2 (List B)?

The attached file doesn´t give me the correct intersection for each item. (15.0 KB)


The first polyline in both lists (all branches) is duplicated.

thanks for the reply. you can remove the shift path component. It doesnt matter. I´m aware of the fact that the first two curves are duplicates. But it should work anyway. (14.0 KB)
