Hello everyone , I am trying to set grid leader from linked models grids. I am facing some error with it in live project.
is there any way , that i can do it with dynamo nodes because i am not good at python.
You have to share your code … … to see how “bad” you are ! 
#paste your bad code here!
let`s see your inputs too, maybe the mistake is in the input!

Ha ha ha . I am very bad in python 
Actually the script is working properly in normal projects but gets error in live project
here is the code :
Grid design.txt (3.5 KB)
thanks in advance .
