Can't make a loop

[Einar_Raknes]

It’s not very clear what you are after. Are you trying to make a group of all elements that are connected?

See this topic, in the end he gives an example with some furniture, looks like he got it working:

How to combine lists with common items?

I want to detect how many groups of elements are placed in a row. With the node GetSurroundingElements from SteamNodes I can get if an element is next to other. If I have four elements one next to other (ABCD), the node back me the collision with AB - ABC - BCD - CD. There is a function for combine all of them in an unique list? (Could exists more groups and groups with different sizes EFGH - IJKLMN…) Thank you!     [combine_list]
