1: How to add Art Libraries: I have some Art libraries I would like to add but not sure how.
How to manipulate text closer together for welding: I have tried different ways to ungroup text to be able to manipulate so I can weld without success.
Sorry it has been a couple of years since I have used lightburn.
Thank you
The libraries can be opened in the library window.
Once you converted the font to paths, you can join/weld them. But not all at once usually, because there are ambiguities depending on the letters. Do one at a time.
Probably best you take a look at the documentation for Art Library, and view the walkthrough video at the top of the page: Art Library - LightBurn Documentation
Looking at the size of that file leads me to believe the file may be corrupted. I would look for a backup of that original to see if you can recover the contents.
