Based on received data from an Excel sheet, I managed to extract excel columns (keys) & (new information) and filter the data based on common key values that exist in sheets and models to extract elements only matching with the key, and I need to assign the matched only with the corresponding new information, but I can’t match or common factor between them
briefly. “Filter elements based on a common key element to as assign on its other parameters the corresponding value from Excel.”
how to link between them between pink and purple group ??!!
Hi Mo, welcome to the forum! 
So if I understand, you want to select elements which match a certain value and then update with a paired value. Dictionaries are going to do all the heavy lifting here as we can group by the values, create a dictionary and then select for the matching values (in an order) and then you can apply the new value in the paired order to your elements.
You will have to clean the nulls / no values in the parts list first as it cannot be a dictionary key
Your values are also already strings so you will not need to convert (numbers cannot be dictionary keys)
i need to set parameter value For WIR Values (PINK) on filtered elements (Purple) knowing that the (WIR) value need to match with filtered 3 only VALUES from construction segments as shown so when i set parameter value i assign on the 3 items not whole 10
Set up a dictionary ‘SEC’ are your keys and ‘WIR’ numbers are your values
Then filter your parts you want to add the ‘WIR’ number buy using just the three ‘SEC’ values
Now you have the parts use the ‘SEC’ value to get the ‘WIR’ number from the dictionary and update the part parameter value.
