How to rearrange the order of the list

Hi,

Now, I'm in the face of the matter to rearrange the order of the list of some rectangles I put below.

These rectangle which is red and green one is currently arranged in the order of blue, and I want to change the order of them into red number...

If you know how to rearrange them, would you teach me it.

Best regards,

Hi Naoki! Use list item to extract 2 and 3 from original list. Cull item 2 and 3 from original list and then list insert (insert your list item in 4 and 5 indexes). Hope helps. Bests.

Thank you so much for your reply, lucas!

Your way is to replace items one by one, right?

That's good, but do you know how to rearrange items arranged in blue into clockwise from 0 o 7.

I have to operate many similar but little different tasks in the same program after this, that's why I ask you.

So, if you know how to rearrange items into clockwise, teach me again.

Best regards,

If the order of the original rectangles is not known, or if it varies, you can sort the rectangles along a circle generated by their center points:

Hi, Jonah! Thank you for your reply and friend request!

I tried to sort rectangles in your way, but something is wrong...

I guess, SortAlongCrv component doesn't work. 8 rectangles are duplicated on a rectangle 0.

Do you know what's wrong? What should I change?

Best

You will need to arrange the rectangles before this definition. This only orders the rectangles in a list. It does not set their positions (nor rotations).
