FreeCAD是多平台。It runs and behaves exactly the same way on Windows Linux and Mac OSX platforms.它运行和行为完全相同的方 式,在Windows Linux和Mac体积平台。 FreeCAD is a full GUI application. FreeCAD 就是一个完整的GUI应用程序。FreeCAD has a complete Graphical User Interface based on the famousFreeCAD拥有完整的图形用户界面基于 名人QtQtframework, with a 3D viewer based on框架,基于3D阅览器Open Inventor开放的发明 家, allowing fast rendering of 3D scenes and a very accessible scene graph representation.快速的渲染中,允许三维场景和 场景图表示非常方便。 FreeCAD also runs as a command line application, with low memory footprint.

FreeCAD作为命令行同样运行应用程序,实现了低 内存占用。In command line mode, FreeCAD runs without its interface, but with all its geometry tools. 在命令行模式,FreeCAD运 行而没有它的界面,但是与它所有的几何工具。It can be, for example, used as server to produce content for other applications.它可 以,例如,作为服务器产生的内容,为其他应用。

作为FreeCAD可进口Python module巨蟒模块, inside other applications that can run python scripts, or in a python console. 在其他应用程序,顾名思义,能跑,或在一条巨蟒控制台。 Like in console mode, the interface part of FreeCAD is unavailable, but all geometry tools are accessible.就像在 控制台模式,界面的一部分是无效的,但所有FreeCAD几何工具是可 存取的。 Plugin/Module framework for late loading of features/data-types. 插件/模块框架的特点/ data-types晚加 载。FreeCAD is divided into a core application and modules, that are loaded only when needed. FreeCAD分为核 心应用程序和加载模块,只需要时。Almost all the tools and geometry types are stored in modules. 几乎所有的工具和几 何类型是储存在模块。Modules behave like plugins, and can be added or removed to an existing installation of FreeCAD.行为举止就像插件模块,也可以添加或删除,到现有的 FreeCAD安装。 Built-in内置scripting脚本framework框架: FreeCAD features a built-in特点:FreeCAD一个内建的Python巨蟒interpreter, and an API that covers almost any part of the application, the interface, the geometry and the representation of this geometry in the 3D viewer. 翻译,和原料药,几乎涵盖了 任何应用程序的一部分,界面几何学的表现形式与这种几何学在3D 阅览器。The interpreter can run single commands up to complex scripts, in fact entire modules can even be programmed completely in Python.单一命令解释器可以跑到复 杂文字,事实上整个模块甚至可以被编程完全在巨蟒。 a modular MSI installer allows flexible installations on Windows systems. 一个模块安装程序允许灵活的设施MSI视窗系 统。Packages for Ubuntu systems are also maintained.包裹 的Ubuntu系统也维持。

文档结构 • •

撤销/重做框架:一切都是撤销/ redoable,访问撤销堆栈, 所以多步可泼水的一段时间。 Transaction management: The undo/redo stack stores document transactions and not single actions, allowing each tool to define exactly what must be undone or redone.交易管理:撤销/重做 堆栈文件而不是简单的商店交易行为,使每个工具来定义 到底应该怎么做或重新调整。 Parametric associative document objects: All objects in a FreeCAD document can be defined by parameters. 文档对象:所有参数结合物体在一种 FreeCAD文档被定义为参数。Those parameters can be modified on the fly, and recomputed anytime. 这些 参数可以进行修改,这只需要更换上和recomputed随时都 可以。The relationship between objects is also stored, so modifying one object also modifies its dependent objects.客体之间的关系也是仓库,所以修改 一个对象,也改变其所依存的物体。 Compound (ZIP based) document save format: FreeCAD documents saved with .fcstd extension can contain many different types of information, such as geometry, scripts or thumbnail icons.基于复合 (ZIP文件保存格式:FreeCAD)一起保存.fcstd文件扩展可 以包含许多不同类型的信息,例如几何、脚本或指甲图标。

用户界面 •

全面定制/小型程序的图形用户界面。The这QtQt-based interface of FreeCAD is entirely accessible via the python interpreter. 基于界面的FreeCAD是完全可以通过这个解释器。 Aside from the simple functions that FreeCAD itself provides to workbenches, the whole Qt framework is accessible too, allowing any operation on the GUI, such as creating, adding, docking, modifying or removing widgets and toolbars.撇开这个简单的函数,FreeCAD workbenches本身提供给整个Qt的框架,是可存取的太,允许任何操作对图形用户接口中,如创造、添 加、修改或删除,对接的组件和工具栏。 Workbench concept: In the FreeCAD interface, tools are grouped by工作台的概念:在 FreeCAD界面,工具是捆绑在一起的workbenchesworkbenches. 。This allows to display only the tools used to accomplish a certain task, keeping the workspace uncluttered and responsive, and the application fast to load.这允许只显示所使用的工具来完成某项任务,保 持清洁的工作空间,并对其应用快速响应负荷。 Built-in Python console with syntax highlighting, autocomplete and class browser: Python commands can be issued directly in FreeCAD and immediately return results, permitting scriptwriters to test functionality on the fly, explore the contents of the modules and easily learn about FreeCAD internals.内置的巨蟒控制台与语法突出,完成的和阶 级的浏览器:蟒蛇的命令可以直接发在FreeCAD和立即回结果,允许的编导测试功能,探讨在飞的内容 的模块和构件FreeCAD轻易了解。 User interaction mirroring on the console: Everything the user does in the FreeCAD interface executes python code, which can be printed on the console and recorded in macros.用户交互镜像在控制台:一切用户界面是在FreeCAD实行巨蟒代码,这能被打印在控制台,并 且记录在宏。 Full macro recording & editing: The python commands issued when the user manipulates the interface can then be recorded, edited if needed, and saved to be reproduced later. 编辑:宏观记录及满时所发出的巨蟒,当用户界面可以操控,如果需要,记录和保存编辑被复制以后。 Thumbnailer (Linux systems only at the moment): The FreeCAD document icons show the contents of the file in most file manager applications such as gnome's nautilus.Linux 系统中只有现在):FreeCAD文件图标显示的内容,这个文件在大多数文件管理器的应用,如侏儒的鹦 鹉螺。
