This is the documentation wiki of FreeCAD. The information contained here is what forms the offline documentation shipped with FreeCAD itself. You have two main ways to browse through the documentation: by exploring user hubs, or by following the manual. It is a work in progress, written by the community of users and developers of FreeCAD. If you find information that is wrong or missing, please help!
The following table lists all the articles of this wiki that form the backbone of the offline documentation shipped with the FreeCAD application. It is already available in several languages:
There is plenty to do inside the FreeCAD project, if you are interested in helping us. There are programming tasks, for C++ or python programmers, but there are also many things you can do even if you cannot code, such as writing documentation, helping newcomers, translating the application and documentation, help packaging the latest release of FreeCAD for your favourite operating system, or simply help other people to discover FreeCAD around you. The help FreeCAD page describes it all with more details. Starting from 2016, FreeCAD is also participating to the Google Summer of Code.
FreeCAD can be compiled on all platforms using cMake. The source code is LGPL-licensed and hosted on https://github.com/FreeCAD/FreeCAD and there are build instructions for Windows, Unix/Linux and MacOSX. The source code documentation is at http://www.freecadweb.org/api/
Check the Development roadmap for news about what is being planned, the Changelog and Roadmap pages on the FreeCAD tracker to see the progresses towards next release, or the Project statistics for even more information about the FreeCAD codebase. All the development communication happens on the forum, so be sure to visit it if you are interested in participating.
