I have tried this umpteen different ways. It doesn’t work for me and I don’t know why.

Subject: Re: Hatch patterns available?

Sorry, I don't know a source of hatch patterns. But it is really easy to create your own. Just make a drawing within a boundary of 100 x 100 units and save that at LibreCAD\resources\patterns, which is the folder where the hatch patterns reside. They are just dxf-files. Or open an existing one from there, edit it, delete the contents and draw new content, then resave at same folder under new name. That's it.
