Hi! I want to combine these two lists of strings. The first item of the first list is added at the end of the first item of the second. How can I add a “.” separator in this case? [image] Thanks!

Thanks @Vikram_Subbaiah , it is really interesting how you use the String.Join with Long Lacing for the separator only before plug it into the List.Combine.

@Einar_Raknes thanks for your approach. I´m really keen on learning more about creating those kind of statements using Code Block.

It is not so difficult. You just put a + (plus sign) between each part you want to join. Strings are quoted with “”. list a + separator + list b. [image] Another example: [image]

Great! @Einar_Raknes is it possible to set the Lacing type (short, long, cross) within the Code Block? [image] What if in the graph above I wanted the lists to read like this: 1.A, 2.A, 3.A and the second list like: 20.B, 21.B, 22.C

@Pablo_Perez_Valdivia Yes, like Kulkul says: You have to use replication guides: [image]

@Kulkul , @Einar_Raknes , thanks guys, really valuable stuff. I´ve learnt a lot. Again, I´m getting closer and closer and then a new question comes up. In the following graph I´ve highlighted in pink the first problem: How can I add the elements of List_B to the end of each subelement of List_A. The…

One possible solution to you second problem @Pablo_Perez_Valdivia [image]

Hi @Vikram_Subbaiah , that works perfect!!! @Einar_Raknes , I realized that I already had the list of elements upstream (Watch node on the left), so I can Set.Parameter in just one go. Here the result: [image] BTW: This is the end part of a larger Definition that identifies the Area a door belong…

@Pablo_Perez_Valdivia

You need to use Replication guides to change lacing in code blocks:

Merge lists with lists with same index
