I have Bobart and followed the you tube tutorial by Depoalo ([url]https://www.youtube.com/watch?v=4NNZcNNw5RI) for importing vectors from a pdf file.

The lines came in fine and are clean. The issue is, it appears instead of one line there are 5 lines laid on top of each other. I have started selecting line by line and deleting the top 4 lines so I am left with one. But this is taking a long time for this specific drawing. Is there a faster way to remove these duplicate lines?
