Friends!
Why is “Flatten” needed in nodes?

If you don’t turn on Flatten, what will happen? Please explain the included and not included Fletten.

don’t exactly get what you mean with “nodes”

:joy:
Flatten combines branches of a “data tree” into a single list, which is not always what you want.

In computer science, if we work with a lot of Data (Like the grasshopper stuff) you will end up with Data that is stored into lists and sub-lists and sub-sub-lists. this can be simplified into describing the data structure as Trees.

In this case sometimes, you need to flatten this structure to a list to make it easier to work with, see screenshot below:

I apologize for another dumb question.
Does Flatten’s change affect the design of the 3D model?

Yes, it certainly can :exclamation: :exclamation: :exclamation:

Your need to understand data trees for success with Grasshopper. Find tutorials because one question at a time won’t get you there. You won’t even know what to ask.
