[LibreCAD](https://www.librecad.org) is a 2D CAD drawing tool
based on the community edition of [QCAD](https://www.qcad.org).
LibreCAD uses the cross-platform framework [Qt](https://www.qt.io/download-open-source/),
which means it works with most operating systems.  
The user interface is translated in over 30 languages.  https://translate.librecad.org

The master branch represents the latest pre-release code,  
and now requires Qt 6.4.0 or newer.  
The 2.2.1 branch requires Qt 5.15.0 or newer.
The 2.2 branch requires Qt 5.2.1 or newer.
The 2.1 branch will be the last to support Qt4.

## DXF Converter
LibreCAD can be used as dxf to a pdf, png or svg converter. For example, to convert a foo.dxf to foo.pdf, foo.png or foo.svg:
```bash
$ librecad dxf2pdf foo.dxf
$ librecad dxf2png foo.dxf
$ librecad dxf2svg foo.dxf
```
