LibreCAD’s latest build - User Manual
This is the LibreCAD User Manual for latest pre release builds.
The manual is work in progress, and probably not up to date with the latest build application.
Any help is welcome to add new features and modifications to this documentation, to close the gap and make the manual more complete.
