FreeCAD

FreeCAD 是通用且开源的三维 CAD/MCAD/CAx/CAE/PLM 建模工具, 目标直指机械工程产品设计,也面向更广泛的工程应用,例如建筑或其他工程领域。FreeCAD 以参数化特征建模为核心功能,基于模块化的软件架构而实现,可在不改动系统核心的的前提下进行功能扩展。

FreeCAD 建立于强大的几何核心 OpenCasCade 之上,采用 Coin 3D 提供的与 Open Inventor 兼容的三维场景模型,并提供丰富的 Python 应用程序接口,其图形交互界面基于 Qt 实现。FreeCAD 能够确保在 Windows, Mac OS X 与 Linux 平台上运行时用户交互界面的一致性。

核心功能

  • 基于 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
  • File:Feature6.jpg
    支持以插件(模块)形式对核心功能进行扩展的模块化的软件架构。所实现的扩展可以像一个全新的应用程序那样复杂,也可像 Python 脚本 或所录制的 macros 那样简单


尚在开发的功能

  • 具备约束求值的草图 (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。
  • 机器人仿真模块,可用于研究机器人运动。该模块目前已具备一个宽泛的图形界面,可仅仅通过图形交互界面进行机器人运动仿真。
  • 渲染模块,可导出三维对象,以供外部渲染工具实现模型渲染,目前仅支持povray,但是将来有望扩展到其他渲染工具。
  • 建筑模块,支持 BIM 风格的工作流程,并兼容 IFC。建筑模块的设计与实现还在社区讨论阶段,见这里

手册

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!

其他

开发动态

开发路线页面可获得有关开发计划的一些新闻,在更改记录路线图页面中可获得当前版本至下一版本发行过程中的一些动态,或者在项目统计页面查阅有关 FreeCAD 代码库的更为详细的信息。有关开发的所有事宜通过论坛沟通交流,如果你有兴趣,那么一定要前往。

源代码

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/LinuxMacOSX

FreeCAD 项目需要你的帮助

FreeCAD 会受益于你的帮助, 可以参与测试与Bug 报告,或者参与指南的撰写。我们也缺乏 Mac OS X 平台的用户,如果你有一台 mac 机器,请帮助我们!另外,也欢迎你参与FreeCAD 本地化翻译工作。如果你熟悉 C++ 或 Python 编程并且愿意参与开发,那就更好了,请到论坛联系我们!

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!


User hubs

Below are the three main entry points to the documentation, for the three broad categories of FreeCAD users:

  • Users hub: For normal users, explains how to install and use the FreeCAD application and the contents of the different workbenches
  • Power users hub: For advanced users, explains how to use macros and python scripting to enhance your workflow
  • Developers hub: For developers, explains how to write code for the FreeCAD application, extend it or use it in your own applications

Manual

The FreeCAD manual is another, more linear way to present the articles contained in this wiki. It forms the backbone of the offline documentation shipped with the FreeCAD application. It is already available in several languages:

Get involved

How to participate

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.

Source code

FreeCAD can be compiled using cMake. The git link is https://github.com/FreeCAD/FreeCAD_sf_master and there are build instructions for Windows, Unix/Linux and MacOSX.

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 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.
