My team designed a building in Archicad, then exported a view as a pdf and imported it into Illustrator to then laser it onto cardboard and build our model.
We have run into the following problem: after having imported the file into Illustrator, we found that all of the lines in the view are layered over one another three times, meaning to avoid the laser engraving each line three times, we have to delete two of the three. Of course, we can do this manually, but it's taking a massive amount of time. Is there a way to delete two of these line layers with just a few clicks?
