FreeCAD is a general all-purpose 3D modeling application, focused on mechanical engineering and related areas, such as other engineering specialties or architecture. It is conceived as a platform for developing any kind of 3D application, but also for doing very specific tasks. For that purpose, its interface is divided into a serie of [[Workbenches]]. Workbenches allow to change the interface contents to display all and only the tools necessary for a specific task, or group of tasks.

引言

FreeCAD 是面向 CAD/CAE 的参数化建模应用程序。目前 FreeCAD 仍在开发阶段,因此不建议在生产中使用它。不过,如果你对 FreeCAD 感到好奇并且想看看它已经具备了哪些功能,欢迎你下载试用。现在,许多功能已经实现,只是有许多功能尚未集成至用户界面。这意味着如果懂得一些 Python 编程知识,你就能够使用 Python 脚本很容易的生成或修改复杂的几何模型了。如果不懂 Python 也没关系,FreeCAD 的现有功能对你应该也有所帮助。请耐心等待,这种状况不久便会有所改善。

在使用过程中,如果你有一些反馈意见或建议,请发到 FreeCAD 论坛中,我们一起商讨!

安装

首先要下载并且安装 FreeCAD,详请可参考下载页面。目前已分别为 Windows (.msi), Ubuntu & Debian (.deb), openSUSE (.rpm) 以及 Mac OS 等操作系统提供了安装包。

FreeCAD 是以通用为目的的三维建模应用程序,主要面向机械工程及相关领域,例如建筑或其他专业领域。在设计上,FreeCAD 被定位为三维应用程序通用的开发平台,也可用于完成一些特定任务。对于这一目的,FreeCAD 的用户界面被划分为一系列的工作台。这些工作台所包含的工具可在用户界面中全部显示,也可以仅显示面向特定任务的那部分工具,或者显示一组任务对应的工具。

因此,FreeCAD 的界面可描述为一个非常简单的容器,该容器具备菜单栏、三维观察区以及用于显示场景与对象信息的边栏面板。边栏面板中的内容可跟随具体的工作台作相应的切换。

第一次运行 FreeCAD 时,所显示的是一个“通用”的工作台,称为“完全工作台”(Complete workbench)。这个工作台简单的聚合了其他工作台业已成熟的工具。由于 FreeCAD 非常年轻,不适于在非常特殊的工作中使用,这个完全工作台可让 FreeCAD 现已具备的功能一览无余。这些工具对于创建一些基本的几何模型已经相当可用了。

Navigating in the 3D space

FreeCAD has two different navigation modes availables, that can be set in the preferences settings dialog. In the default mode, zooming is made with the Mouse wheel, panning with the Middle mouse button, and rotating with the Left mouse button and Middle mouse button simultaneously. Selecting an object is made simply by clicking on it with the Left mouse button, with CTRL pressed if you want to select several objects.

You also have several view presets (top view, front view, etc) available in the View menu and on the View toolbar, and by numeric shortcuts (1, 2, etc...)

Scripting

And finally, one of the most powerful features of FreeCAD is the scripting environment. From the integrated python console (or from any other external python script), you can gain access to almost any part of FreeCAD, create or modify geometry, modify the representation of those objects in the 3D scene or access and modify the FreeCAD interface. Python scripting can also be used in macros, which provide an easy method to create custom commands.
