I extracted a part of the plans from the data list and changed their angles, but I can’t replace the changed plans with the corresponding position in the original data, because my list has already been grafted, this may be a very simple thing, but I’ve tried many times to no avail, thanks in advance for your help!
No, you’re not. Data trees and working with lists aren’t intuitive to most people but thankfully most all list/data tree problems that can exist have had solutions found for them in these forums so that’s good news!
