Hi, @Imran_Hakim

how does your data structure in gh look like ?

Do you just select points and lines randomly in Rhino and you need to sort them first before you extract a sequence or ist the data structure in gh already sorted ?

thanks again!!!

hi eef, so sorry, i just tried out your solution but it seems its not working, maybe you could try to debug?

Please extract that part out of your gh file.
Use internalise data to save your data in the file
Then upload here.

My guess it, is something with the tree structure. but we have to see your file to see whats going on.

When working with lists it is important to see how these lists are positioned in the data tree.

• all in 1 list
• in seperate branches
• or on different levels.
  It is like a christmas tree, not all candles are on the same branch
