Hi Ujaval. Can I ask about inserting the 'Refactor fields' in the QGIS model? I have calculated the total length of the highways by district. However, I am stuck in deleting the unnecessary fields in the attribute table so that the final output will only display "district" and "total_length". Thank you for the help.

Hello Ujaval - I am trying to use join attribute by location to join an output (extracted national/state highway with length in km) to district layer and I am getting and error saying no results. Need your guidance to move forward. Thanks !

Hi, thanks for this amazing course. I need help with this assignment. I spent many hours using my previous knowledge, and ChatGPT, but could not find the right expression to connect the Enum input with the Extract by Expression.

Hello Ujaval, I have loved working through this exercise; I came to the proper result, perhaps not through the most optimal route. In your documentation you hint at the use of 'refactor fields', however I achieved my results without utilizing this particular element; without giving anything away, would you say that its primary purpose is in reducing and renaming in the later portion of the exercise?
