Welcome to the LibreCAD Wiki!

Introduction LibreCAD (originally CADuntu) is a free and open-source 2D CAD application, which uses Qt (a cross-platform application framework). The project started around 2010 as a fork of QCAD 2.0.5.0. Support for reading DWG files was added with libdxfrw. Support for writing MakerCAM SVG files was also added. The release of 2.1.0 increased customization of the user interface. You can now create custom toolbars and menus, and dramatically change the appearance (among other things).

Things We Need Help Wanted. We welcome Open Source Developers to join us, to improve this free drawing tool in exciting fields such as: Contribute to the wiki based on your accumulated knowledge. If you have figured out a feature in LibreCAD, please add to our wiki to help other users. Implement more command line support for actions. Currently, there are many actions there without command line support, we need to complete this part of implementation and add the relevant documents. Add support for native text based on Qt fonts. Right now, only stick fonts are supported. When the usage doesn't require stick fonts, native Qt fonts should be used for better multi-language support and efficiency Implement a new and robust hatch generating algorithm The current spline implementation is not efficient, we would like to replace it with a better spline implementation and add both spline and Bezier support as well, see Bezier We have implemented new math support for hyperbola and parabola. Implementation support for hyperbola/parabola entities would make LibreCAD capable of doing all conic sections. Feature tweaking and bug fixing for printing/painter Refactor header files to speed up the building process, support for pch headers Document writers to help building wiki and user manuals Quality Assurance, bug hunting Documentation Translation Improving tangent point detection Improving the plugin system You might also want to consider contributing to the next generation of LibreCAD.
