I have a question regarding the editing tools. I have made this selections of lines then used the "union" tool to make them into one entity but the lines that were merged together are still on my shapefile "under" my bigger entity. (see picture)
Is there a way to delete all of the lines I used to create the bigger entity without having to select them one by one ?
I can't select in my attribute table because I have other lines that I need to keep.
