Question
Unable to select anything other than grid squares despite coverting it to an AI format?
I am trying to edit this PDF so I converted it into AI format in illustrator however I still can't edit it and the only thing I can select is these grid squares? I have tried everthing to try fixing this but I just cannot find a way to be able to select anything. I can select the individual squares and isolate them but i can only move and delete them not select any lines. Please help
