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。

与许多现代3DCAD建模软件一样,FreeCAD具有许多2D组件,以便绘制2D形状或从3D模型中提取设计细节以创建2D生产图纸,但是直接的2D绘图(AutoCAD LT)不是FreeCAD的功能重点,也不是动画或生物形体(如Maya3ds MaxBlenderCinema 4D),尽管由于其广泛的适应性,FreeCAD可能在比当前焦点更广泛的领域中变得有用。

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!
