Hi @Japhy! Thanks for replying. I am attaching the grasshopper file for your reference.
To elaborate problem, the LIST-1 contains the column ID’s in the first index ‘0’ say ‘Column ID = 1’.
LIST-2 is having the column ID’s in first index ‘0’ and its size ID in index ‘2’ say ‘Column ID = 1’ and its ‘Size ID = PO-C21A-10T32-600D-C90’ . The LIST-3 is having the combination of Size ID and the size say for ‘Size ID = PO-C21A-10T32-600D-C90’ the size is ‘600’
So, i need get the size ID for LIST-2 by comparing items in LIST-1 and get the size from LIST-3 by comparing the size ID.
Finally the column ID=1 has to get the size as 600.
