Add style to your LibreCAD drawings by creating and using custom hatch patterns. LibreCAD comes packaged with 62 patterns – I counted – that will work for most cases. But there have been times when I needed a unique hatch pattern. Creating your own hatch patterns is literally the same as creating any other design inside of LibreCAD. By convention, patterns have the origin of 0,0 and do not exceed 100,100.
