Introduction

选择你操作系统

FreeCAD 是一个真正的跨平台应用程序,基于世界知名的 Qt 框架之上。这意味着 FreeCAD 外观和行为与在 Windows, Linux 和 Mac 上是一致的。然而,安装过程在每个操作系统上是有所不同的。在下面选择你的操作系统以获得更多细节关于如何安装 FreeCAD。

Help files

The offline documentation is not shipped with all installers, but it is available as a separate package. See the Installing Helpfile page for more information.

External workbenches

除了默认捆绑在 FreeCAD 的 工作台 以外,还有由社区成员制作的一堆很有用额外工作台和模块在网络持续增长。几个进行中的成果是收集它们和令它们方便地展示给你。下面是它们的列表。

FreeCAD支持的外部软件

FreeCAD支持大量开包即用的外部软件。这就意味着:您只需简单地安装想用的软件,在下次重新开启FreeCAD后便可自动在其中使用此软件了。此过程中无需对其进行重新编译。本节的目标便是提供所有此类软件包的列表,同时给出在FreeCAD中使用这些软件的有关信息以及它们的获取方式。

FreeCAD supports several third party software packages out of the box. In many cases all you need to do is install the software, and when FreeCAD is restarted it will automatically find and be able to use it. This section aims to provide a list of such software packages, together with some information about where they are used in FreeCAD and where they can be downloaded.

Support

GitPython

一种用于与Git仓库进行交互的python库。FreeCAD中的此功能在还处于开发状态中。插件管理器可利用此库从Git仓库中导入各种扩展插件。此项目托管在GitHub中的 https://github.com/gitpython-developers/GitPython

GitPython is a library to interact with Git repositories. The Addon Manager can use this library. GitPython is included in the FreeCAD installers for Windows and Mac.

GraphViz

GraphViz是一款开源的图形可视化(graph visualization)软件。在FreeCAD中可通过Tools → Dependency Graph...来令它生成依赖图。它的主页位于 https://www.graphviz.org

GraphViz is an open source graph visualization software. It is used by the Std DependencyGraph tool.

OpenCAMLib

一种提供计算机辅助制造(computer aided manufacturing (CAM))算法的开源库。在FreeCAD中的路径工作台(Path Workbench)会用到它。OpenCAMLib的首页位于 http://www.anderswallin.net/CAM/

OpenCAMLib is an open source library of computer aided manufacturing (CAM) algorithms. It is used in the Path Workbench. See the OpenCamLib page for installation instructions.

OpenSCAD

此程序化3D实体CAD建模工具是另一种基于结构实体几何(Constructive Solid Geometry (CSG))的CAD软件。这意味着:它不能处理网格,而是专用于操作实体几何图形。在FreeCAD中,可通过在File → ImportFile → Export菜单中选择OpenSCAD CSG formatOpenSCAD format文件类型来导入、导出OpenSCAD所创建的文件。您可以从 https://www.openscad.org 处搞到OpenSCAD。

OpenSCAD is a solid 3D modeller. The OpenSCAD Workbench depends on this software and the Mesh Workbench uses it for its Boolean tools. It is also required for the import of SCAD files with the Std Import tool.

File formats

All software in this section will be used by the Std Import or Std Export tools.

CAD Exchanger

此为一种用于交换CAD中所用各种文件格式的专用闭源应用程序。您可以用它把专有闭源的格式转换为FreeCAD可访问的格式。本工具的主页为 https://cadexchanger.com/ ,在此,您可以下载该软件的评估版或购买该软件的使用许可。

CADExchanger is a commercial application for exchanging various CAD file formats. There is an external workbench to use this application in FreeCAD.

DXF Importer

FreeCAD中有一个以C++编写的DXF原生导入、导出工具。 此导入器当前还未实现DXF格式的所有特性。如果您用到了那些还没有实现的特性,可通过在Edit → Preferences → Import-Export中选择Use legacy python importer选项来开启基于python的旧版导入/导出工具。您还可以通过Allow FreeCAD to automatically download and update the DXF libaries选项令FreeCAD自动从 https://github.com/yorikvanhavre/Draft-dxf-importer 下载所需文件,或自己手动下载。被选中的导入 / 导出工具用于实现File → ImportFile → ExportAutoDesk DXF 2D文件格式的导入导出工作。(译注:简而言之,原生导入导出器有新旧两种,旧版以python编写,功能完整但速度较慢;新版由C++编写,速度快但功能还未完整实现。)

FreeCAD has a native importer and exporter for DXF files, programmed in C++. Currently they do not implement all features of the DXF format. For those features the legacy Python importer and exporter are still available. These require the Draft-dxf-importer Python library. See the FreeCAD and DXF Import page for more information.

ifcOpenShell

IfcOpenShell是一种用来处理建筑设计所用Industry Foundation Classes (IFC)文件格式的库。可在建筑工作台(Arch Workbench)中通过Arch → Utilities → Ifc Explorer来访问它。ifcOpenShell的主页位于 http://ifcopenshell.org

IfcOpenShell is a library for working with the Industry Foundation Classes (IFC) file format used in architectural design. The library is also used by the Arch IfcExplorer (version 0.18 and below) and BIM IfcExplorer tools. IfcOpenShell is included in the FreeCAD installers for Windows and Mac.

IfcJson

IfcJson is a library required for exporting to the IFCJSON file format. IFCJSON is a new IFC format that is not yet supported by many applications.

LibreDWG

Support for LibreDWG is still experimental. Like the ODA File Converter it can convert DWG to DXF files which FreeCAD can then import. See the FreeCAD and DWG Import page for more information.

ODA文件转换器

ODA文件转换器是一种专有、闭源、二进制且可自由使用的应用程序,用于导入、导出DWG 与 DXF 文件格式。在 FreeCAD中的File → ImportFile → Export菜单里选择AutoDesk DWG 2D文件类型时便会用到它。可从 https://www.opendesign.com/guestfiles/oda_file_converter 下载它。

The ODA File Converter is a free application to convert between several versions of DWG and DXF files. FreeCAD requires this converter, or LibreDWG, to import DWG files. See the FreeCAD and DWG Import page for more information.

pycollada

Pycollada,又名python-collada,是一款用来读写COLLADA文档(一种用于交换3D场景与元素的标准)的Python库。如果您安装了pycollada,就可以通过在File → ImportFile → Export命令中选择COLLADA文件类型,以COLLADA导入/导出场景。此项目托管于GitHub中的 https://pycollada.github.io/ ,您可以从 https://github.com/pycollada/pycollada/releases/ 下载其发行版。

Pycollada, also known as python-collada, is a Python library to read and write Collada (DAE) files. Pycollada is included in the FreeCAD installers for Windows and Mac.

POVRay is a well-known ray-tracer which can render photo-realistic images. It is one of two render engines currently supported by the Raytracing Workbench.

LuxCoreRender

LuxCoreRender,也作LuxRender,FreeCAD中当前支持的两种渲染引擎之一。在光线追踪工作台(Raytracing Workbench)的工作流程中会用到它。FreeCAD目前仅支持老旧过时的LuxRender-1.x。如果您想帮助FreeCAD更新至新的LuxCoreRender-2,请联系光线追踪项目的工作团队。您可以从LuxCoreRender的GitHub发行页面 https://github.com/LuxCoreRender/LuxCore/releases 处下载LuxRender-1.6。LuxCoreRender项目的当前主页为 https://www.luxcorerender.org

LuxCoreRender, also known as LuxRender, is the other render engine supported by the Raytracing Workbench. Only the old and abandoned LuxRender-1.x versions can be used. LuxRender-1.6 can be downloaded from the LuxCoreRender GitHub release page.

Finite element

CalculiX

CalculiX是两种有限元包的组合套件:

  • CalculiX CrunchiX, 或calculix-ccx为一种有限元求解器(FEM solver)。
  • CalculiX GraphiX, 或calculix-cgx为一种显示求解器计算结果的GUI前端。
