Hello again,
can someone help me restructing the two list into one list , in a order that gives me an ability to draw the shape between every four points? i mean i should be able to have the shapes seperated in the end. thank you

P.S. This is another way to use the ‘Tree/List Viewer’, where the ‘path idx’ slider chooses the “quad” and the ‘list idx’ slider chooses the edge (yellow).

Relative Item is like, practically, a Shift List, but for trees. You shift branch paths n times with “{n}” and the items in branches m times with “(m)”: “{n}(m)”. The first output is like the input tree, but cut properly in case the wrappers are disabled (if n=3, m=2, the last three branches and the last two items per branch will disappear). The second output returns the shifted tree.

I am shifting one time for and one time back to get the lines in the correct order, than I merge them to pairs of 2. You can observe it by the point order and the param viewer like this:
