Boolean tools not highlighting

I am trying to weld the two highlighted shapes together, but none of my boolean tools are able to be clicked. It was working fine just a bit ago. I have tried closing and reopening LightBurn. I tried it on a completely different file and it works as it should. Can anyone give me some other ideas to try? Thanks!

Hard to tell from the picture. One of the shapes is probably open. Zoom in and look for a break in the line.

Or Edit → Select Open Shapes, then Edit → Close Path as needed.

You can drop the .lbrn2 project file here and we can help you diagnose what is going on… it’s probably an open shape…


It absolutely was an open shape problem. Thanks to all for helping with that!
