I have a question. Here's a part of my artwork: and I want to erase the lines between the squares, just the lines between the squares. If you don't understand what I'm saying here's a picture of what I want to do: [![enter image description here][1]][1] all the black lines which are below the red lines have to be erased. **My question is if I can erase them by drawing a line above the black lines with some tool, like cutting the black lines between the squares and not the lines that are in the squares?** [1]: https://i.sstatic.net/iyf3w.png
