Hi,
I was following a tutorial video on YouTube however when I tried to boundary surface to burp | burp it showed “planar surface routine returned no results”. Not sure which part went wrong though and just wondering is there anyway to solve this.
Thank you

If you want to keep the data strucuture, you could also use Clean Tree, with the Remove Empty (E) option set to true
Sry just wondering how would I be connecting the clean tree? It’s my first time coming across to it haha.
Here it’s how to do that. Even I suggested Flatten to give you the quick solution. Mostly everyone who has strong knowledge in grasshopper doesn’t suggest the use of Flatten.

You don’t have to flatten or clean the tree - orange color is just a warning - for advanced use, and in many cases you may want to keep the empty branches/nulls to troubleshoot the dataflow… So I don’t think it is a good habit to get into: Flatten / Clean…
just sayin…

These are completely the user’s choice. How effectively He/ She wants to handle the Data Tree structure in grasshopper.
And here I’m linking some interesting topics for your insight. @dzhiyang9671
