FreeCAD是一个通用参数化3D CAD建模软件。它的开发完全是开源的(LGPL许可证)。 FreeCAD直接针对机械工程产品设计,但也适用于更广泛的工程设计用途,如建筑或其他工程专业。

FreeCAD的工具类似于CATIASolidWorksSolid Edge,因此它属于CADPLMCAXCAE类软件。 它是一个基于特征的参数化建模工具,具有模块化软件架构,可以在不修改核心系统的情况下轻松提供附加功能。

As with many modern 3D CAD 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 AutoCAD LT) is not the focus, neither are animation or organic shapes (like Maya, 3ds Max, Blender or Cinema 4D), although, thanks to its wide adaptability, FreeCAD might become useful in a much broader area than its current focus.

FreeCAD makes heavy use of all the great open-source libraries that exist out there in the field of Scientific Computing. Among them are OpenCascade, a powerful CAD kernel, Coin3D, an incarnation of Open Inventor, Qt, the world-famous UI framework, and Python, one of the best scripting languages available. FreeCAD itself can also be used as a library by other programs.

FreeCAD is also fully multi-platform, and currently runs flawlessly on Windows and Linux/Unix and Mac OSX systems, with the exact same look and functionality on all platforms.

For more information about FreeCAD's capabilities, take a look at the Feature list, the latest release notes or the Getting started articles, or see more screenshots.

About the FreeCAD project

The FreeCAD project was started as far back as 2001, as described in its history page.

FreeCAD is maintained and developed by a community of enthusiastic developers and users (see the contributors 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 FreeCAD forum, where most of the ideas and decisions are discussed. Feel free to join us there!
