Hello everyone, when cutting a map I came across this problem that I wanted to “trim” a few lines that I got from my data source, ideally by applying a boolean with a bounding box. See the attached screenshot. However as I found out booleans only seem to be working with closed shapes. Now this can’t be so hard to achieve. Any way to do this I’m missing? Thank you! ![test](https://forum.lightburnsoftware.com/uploads/default/original/3X/0/1/018a991ec42bb93bc9a7db97e0ce0a43deab9cf3.jpeg) ---

Ok I guess I was a bit too quick as I now found this post: > [@Challenges with boolean subtract tool](https://forum.lightburnsoftware.com/t/challenges-with-boolean-subtract-tool/13815/2): > > Boolean operations work only on enclosed areas. If you want to just trim a line, the simplest way for now is to use the I (insert) and B (break) functions with Edit Nodes, then just delete the line segment you don’t want. For example, if I want to trim the black line to be within the red box: [image] Select the black line, then click the Edit Nodes button (under the hexagon on the left toolbar): [image] Zoom in (mouse wheel) to where they cross: [image] Hover the mouse over the intersect… However, they say they have a line trimming function in the works but that was almost three years ago. Any news on that? ---

I can’t quite tell but are you trying to crop away the parts of the map that are outside one of the defined rectangles? If so, try this: 1. Select all parts of map 2. Add bounding rectangle to selection 3. Tools-\>Cut Shapes 4. That should leave you with 2 grouped objects: everything within the bounding rectangle and everything outside the bounding rectangle 5. Discard the unwanted portion ---

Thanks, but this is about closed shapes, which is exactly the problem. It doesn’t work for lines. ---

Awesome, that totally did the trick. Thank you very much! ---
