- Open CASCADE Technology 的完整的几何核心，对 brep, nurbs, 布尔运算与倒角 (fillet) 等概念提供原生支持，可完成复杂形状类型的三维运算
- 草图 (Sketcher) 模块，以实现具有几何约束的二维形状草图建模。目前 草图模块支持多种几何约束类型，可使用它们作为 FreeCAD 中其他对象的构建基础。
- 工程制图 (Drawing sheets)模块，用于生成三维模型的二维视图，并能以 SVG 或 PDF 格式输出。该模块虽然仍缺乏许多功能，但是已经具备了强大的 Python 接口支持。
FreeCAD 手册提供致力于提供有关 FreeCAD 使用的最好的文档，依赖于社区的努力该文当尚在撰写中，目前已有多种语言的版本。这份文档依然缺乏许多信息，如果你有空闲时间请给予帮助!
FreeCAD 可通过 cMake 或 autotools 进行编译，SVN 代码仓库地址位于 https://free-cad.svn.sourceforge.net/svnroot/free-cad/trunk ，编译指南可根据操作系统环境参考 Windows, Unix/Linux 与 MacOSX。
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!
Users hub: This page contains documentation useful for FreeCAD users in general: a list of all the workbenches, detailed instructions on how to install and use the FreeCAD application, tutorials, and all you need to get started.
Power users hub: This page gathers documentation for advanced users and people interested in writing python scripts. You will also find there a repository of macros, instructions on how to install and use them, and more information about customizing FreeCAD to your specific needs.
Developers hub: This section contains material for developers: How to compile FreeCAD yourself, how the FreeCAD source code is structured and how to navigate in it, and how to develop new workbenches, or embed FreeCAD in your own application.
The FreeCAD manual is another, more linear way to present the information contained in this wiki. It is made to be read like a book, and will gently introduce you to many other pages from the hubs above. ebook versions are also available, as well as a couple of translations in pdf format.
Table of contents
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:
How to participate
There is plenty to do inside the FreeCAD project, if you are interested in helping us. Of course, 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 and editing the wiki (en)
- helping newcomers
- translating the application and documentation
- helping with the packaging of the latest release of FreeCAD for your favourite operating system
- helping other people around you to discover FreeCAD.
The help FreeCAD page describes it all with more details. Starting from 2016, FreeCAD also participates in the Google Summer of Code. The Contributors hub page is another effort to gather the possible ways to help and contribute to the FreeCAD project.
FreeCAD can be compiled on all platforms using CMake. The source code is LGPL-licensed and hosted on GitHub and mirrored on GitLab and CodeBerg. There are build instructions for Windows, Unix/Linux and MacOS. The source code documentation is hosted here, generated by Doxygen, and documented on the wiki.
About the development
Check the Development roadmap for news about what is being planned, the Changelog and Roadmap pages on the FreeCAD tracker to see the progress 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.
