5.3 Data Tree Operations in Grasshopper - Intro to Parametric Modeling

In this video, I review the two most common operations that can be done in Grasshopper at the level of the tree structure: grafting and flattening, discuss their importance, and show examples.

Dear Jose, This is the best series I have seen online, thank you for breaking it down and making so much sense with the content. I am currently watching your graduate series and enjoying the two videos on Rhino Common the most. Your career is interesting to follow and try and catch up to but I think that might be impossible for me. Keep going, keep going, keep going! Best, Michael Wickerson

whenever I forget core definition in GH, I found your video. Thank a lot Mr Jose Luis

[@ricoq2008]

simple .... you are the best. No one has ever done one of GH's most difficult operations so well

14:16 Grafting for sure simply because it saves the information of the structuring of the data that i've been building throughout the script whereas flattening will simply lose it (im kinda cheating here bc i watched the "deal with trees" video prior lol)

Thank you very much。

we start dividing a surface and we have a tree that is made of three levels of branches [0;0;0]. It means that the only three branches in our structures are identified by the last zero. The other two zero what stand for? If we flatten the tree we have just one zero [0], instead of [0;0] and this means we move to a three level structure into an one level one. Flattening removes every branch at every level. How we can delete a single level? With graft component levels are four. what prevent to have [0;0;0;i] with i from zero to number of elements instead of [0;0; i; j ] ?

What it is still unclear to me is how to create a tree with two lists because entwine doesnt actually do what I want. Any idea?
