<p><b>FreeCAD</b>的功能目的是成为一个3D <a rel="nofollow" class="external text" href="http://en.wikipedia.org/wiki/CAD"><b>CAD</b></a> 建模工具。她的开发完全遵循 <a rel="nofollow" class="external text" href="http://en.wikipedia.org/wiki/Open_source">Open Source</a> (GPL & LGPL License)协议。 FreeCAD的目标直指 <a rel="nofollow" class="external text" href="http://en.wikipedia.org/wiki/Mechanical_engineering">机械工程</a> 、 <a rel="nofollow" class="external text" href="http://en.wikipedia.org/wiki/Product_design">产品设计</a> ，当然也适合工程行业内的其他广大用户，比如建筑或者其他特殊工程行业。

</p><p>FreeCAD的功能特征类似<a rel="nofollow" class="external text" href="http://en.wikipedia.org/wiki/Catia">Catia</a>, <a rel="nofollow" class="external text" href="http://en.wikipedia.org/wiki/Solidworks">SolidWorks</a> 或 <a rel="nofollow" class="external text" href="http://en.wikipedia.org/wiki/Solid_Edge">Solid Edge</a>, 因此也可以使用关键词 <a rel="nofollow" class="external text" href="http://en.wikipedia.org/wiki/CAD"><b>MCAD</b></a>, <a rel="nofollow" class="external text" href="http://en.wikipedia.org/wiki/Product_Lifecycle_Management"><b>PLM</b></a>, <a rel="nofollow" class="external text" href="http://en.wikipedia.org/wiki/CAx"><b>CAx</b></a> 以及 <a rel="nofollow" class="external text" href="http://en.wikipedia.org/wiki/Computer-aided_engineering"><b>CAE</b></a>. 她是一个 <a rel="nofollow" class="external text" href="http://en.wikipedia.org/wiki/Parametric_feature_based_modeler">功能化的参数化建模工具</a> ，是一个模块化的CAD核心环境，你可以在不修改核心程序的基础上为其开发插件、功能模块。
|
||
</p><p>和其他3D <a rel="nofollow" class="external text" href="http://en.wikipedia.org/wiki/CAD">CAD</a>建模工具一样，她也将拥有一个2D组件来将3D模型的准确设计信息转化为2D的产品图纸，二维静态图纸(比如: <a rel="nofollow" class="external text" href="http://en.wikipedia.org/wiki/AutoCAD#AutoCAD_LT">AutoCAD LT</a>) 并不准确、动态或者有零件关系等概念（译者:仅仅是一些线条而已)(比如: <a rel="nofollow" class="external text" href="http://en.wikipedia.org/wiki/Maya_(software)">Maya</a>, <a rel="nofollow" class="external text" href="http://en.wikipedia.org/wiki/3ds_Max">3ds Max</a> 或 <a rel="nofollow" class="external text" href="http://en.wikipedia.org/wiki/CINEMA_4D">Cinema 4D</a>), 因此，得益于FreeCAD可以被广泛地改写（添加功能模块）, 她将比目前更加有用。
|
||
</p><p>FreeCAD另外一个值得注意关注的是深度应用所有强大的已有开源库，例如<a rel="nofollow" class="external text" href="http://en.wikipedia.org/wiki/Scientific_Computation">计算机科学</a>. 其中包含 <a rel="nofollow" class="external text" href="http://OpenCascade.org">OpenCascade</a>, 强大的CAD内核, <a rel="nofollow" class="external text" href="http://Coin3D.org">Coin3D</a>(是 <a rel="nofollow" class="external text" href="http://en.wikipedia.org/wiki/Open_Inventor">OpenInventor</a>的进化版本), <a rel="nofollow" class="external text" href="http://www.qtsoftware.com/">Qt</a>,著名的UI库,<a rel="nofollow" class="external text" href="http://www.python.org">Python</a>, 是目前最好的脚本语言。当然FreeCAD自身也可以被其他项目作为库来使用。
|
||
</p><p>FreeCAD是一个真正的<a rel="nofollow" class="external text" href="http://en.wikipedia.org/wiki/Cross-platform">多平台程序</a>, 目前可在Windows、Linux/Unix以及Mac OSX系统上完美运行，并在所有平台上拥有一样的外观和功能。

<p>FreeCAD features tools similar to <a rel="nofollow" class="external text" href="http://en.wikipedia.org/wiki/Catia">Catia</a>, <a rel="nofollow" class="external text" href="http://en.wikipedia.org/wiki/Solidworks">SolidWorks</a> or <a rel="nofollow" class="external text" href="http://en.wikipedia.org/wiki/Solid_Edge">Solid Edge</a>, and therefore also falls into the category of <a rel="nofollow" class="external text" href="http://en.wikipedia.org/wiki/CAD"><b>MCAD</b></a>, <a rel="nofollow" class="external text" href="http://en.wikipedia.org/wiki/Product_Lifecycle_Management"><b>PLM</b></a>, <a rel="nofollow" class="external text" href="http://en.wikipedia.org/wiki/CAx"><b>CAx</b></a> and <a rel="nofollow" class="external text" href="http://en.wikipedia.org/wiki/Computer-aided_engineering"><b>CAE</b></a>. It is a <a rel="nofollow" class="external text" href="http://en.wikipedia.org/wiki/Parametric_feature_based_modeler">feature based parametric modeler</a> with a modular software architecture which makes it easy to provide additional functionality without modifying the core system.
|
||
</p><p>As with many modern 3D <a rel="nofollow" class="external text" href="http://en.wikipedia.org/wiki/CAD">CAD</a> modelers it has many 2D components in order to sketch 2D shapes or extract design details from the 3D model to create 2D production drawings, but direct 2D drawing (like <a rel="nofollow" class="external text" href="http://en.wikipedia.org/wiki/AutoCAD#AutoCAD_LT">AutoCAD LT</a>) is not the focus, neither are animation or organic shapes (like <a rel="nofollow" class="external text" href="http://en.wikipedia.org/wiki/Maya_(software)">Maya</a>, <a rel="nofollow" class="external text" href="http://en.wikipedia.org/wiki/3ds_Max">3ds Max</a>, <a rel="nofollow" class="external text" href="http://en.wikipedia.org/wiki/Blender_%28software%29">Blender</a> or <a rel="nofollow" class="external text" href="http://en.wikipedia.org/wiki/CINEMA_4D">Cinema 4D</a>), although, thanks to its wide adaptability, FreeCAD might become useful in a much broader area than its current focus.
|
||
</p><p>FreeCAD makes heavy use of all the great open-source libraries that exist out there in the field of <a rel="nofollow" class="external text" href="http://en.wikipedia.org/wiki/Scientific_Computation">Scientific Computing</a>. Among them are <a rel="nofollow" class="external text" href="http://OpenCascade.org">OpenCascade</a>, a powerful CAD kernel, <a rel="nofollow" class="external text" href="http://www.Coin3D.org">Coin3D</a>, an incarnation of <a rel="nofollow" class="external text" href="http://en.wikipedia.org/wiki/Open_Inventor">Open Inventor</a>, <a rel="nofollow" class="external text" href="http://www.qtsoftware.com/">Qt</a>, the world-famous UI framework, and <a rel="nofollow" class="external text" href="http://www.python.org">Python</a>, one of the best scripting languages available. FreeCAD itself can also be used as a library by other programs.
|
||
</p><p>FreeCAD is also fully <a rel="nofollow" class="external text" href="http://en.wikipedia.org/wiki/Cross-platform">multi-platform</a>, and currently runs flawlessly on Windows and Linux/Unix and Mac OSX systems, with the exact same look and functionality on all platforms.

<h3><span class="mw-headline" id="About_the_FreeCAD_project">About the FreeCAD project</span></h3>
|
||
<p>The FreeCAD project was started as far as 2001, as described in its <a href="History.html" title="History">history</a> page.
|
||
</p><p>FreeCAD is maintained and developed by a community of enthusiastic developers and users (see the <a href="Contributors.html" title="Contributors">contributors</a> page). They work on FreeCAD voluntarily, in their free time. They cannot guarantee that FreeCAD contains or will contain everything you might wish, but they will usually do their best! The community gathers on the <a rel="nofollow" class="external text" href="http://forum.freecadweb.org">FreeCAD forum</a>, where most of the ideas and decisions are discussed. Feel free to join us there!
