LIBRECAD — A professional CAD System.
LibreCAD is a professional CAD System. With LibreCAD you can easily construct and change drawings with ISO-texts and many other features and save them as DXF-files. These DXF-files are the interface to many CAD-systems such as AutoCAD(R) and many others.
LibreCAD has no special invocation parameters.
We are very sorry but could not include the manual because of License issues with the manual from the original QCad CE edition. However, we are working to create a new manual specifically for LibreCAD.

There are some wonderful people on the forum and IRC channel that can give you a hand to get going.
We are sure you will enjoy LibreCAD as much as we do, even without a manual.
