Installing additional components/hr

Choose Your Operating System
FreeCAD is a truly multi-platform application, developed with the world-renowned Qt framework. This means FreeCAD looks and acts the same on Windows, Linux and Mac. However, the installation procedure is a little different for each operating system. Choose your operating system for details on installing FreeCAD.

Installing additional contents
The offline documentation is not shipped with all installers, but it is available as a separate package; see Installing a helpfile.

Apart from the default workbenches bundled with FreeCAD, there is a growing collection of useful additional workbenches and modules made by community members available on the web. Several efforts are in progress to gather them and make them available to you in a convenient way. They are listed below.

Since these workbenches are not part of the official FreeCAD package and not supported by the core FreeCAD team, you should read the information provided with them, to make sure you know what you are installing. Bug reports and feature requests should be made directly to each addon developer.

Spremište FreeCAD-dodataka (addons)
As of FreeCAD 0.17, the addons can be managed directly from the menu, so there is no need to install the macro mentioned here.

This is a gathering of useful workbenches, using the git submodules system, which allows keeping constantly updated contents. The FreeCAD-addons repository can be found at https://github.com/FreeCAD/FreeCAD-addons. This repository features an installer macro that can be launched from inside FreeCAD that will list, download, and install any of the addons automatically.

With FreeCAD 0.17 and higher install use the Addon Manager.

*With FreeCAD 0.16 and older versions, install the addon installer macro:
 * 1) Right-click on addons_installer.FCMacro and choose Save as...
 * 2) Place the downloaded macro in your FreeCAD Macros folder. The FreeCAD Macros folder location is indicated in menu :
 * 1) Restart FreeCAD. The addons installer will now be listed in menu  and can be launched by selecting it then clicking the  button:

The pluginloader addon
The plugin loader is a much more elaborate way to install and manage additional content for FreeCAD. Install it with the method above, or following the instructions on the pluginloader page.

The pluginloader addon has been superceded by the Addon Manager.

Ručna instalacija
External workbenches, when they are fully programmed in Python (which is the majority) can be easily installed manually, simply by downloading them (clicking the or  buttons on GitHub), and placing them in your user's  folder (or in the  folder if they are macros). Refer to the instructions on each addon page for complete information.

Notes for users with 32-bit system and FreeCAD 0.16.6706
After attempts to install, the additional workbenches may not be available. In this case
 * hold the report panel open while starting FreeCAD, and read the error
 * see this forum thread: (Solved)Assembly2 in Version: 0.16.5602 (Git)

External software supported by FreeCAD
FreeCAD supports a whole lot of external software packages out of the box. This means, you just need to install the software and it will be automatically available, the next time you start it. There's no need to recompile it. This section aims to provide a list of all such software packages, together with some information of where it's used in FreeCAD and where you can grab them.

CAD Exchanger
A proprietary, closed source application for exchanging various file formats used in CAD. You can use it to convert proprietary, closed formats into a format which is accessible by FreeCAD. The homepage is at https://cadexchanger.com/ where you can download an evaluation version or purchase a license for the application.

CalculiX
CalculiX is a suite of two finite element packages:
 * CalculiX CrunchiX, or, is a FEM solver.
 * CalculiX GraphiX, or, is a GUI frontend to display the results of the solver.

Only the solver is supported by FreeCAD. It can be accessed from the FEM Workbench through. There's a standard and experimental solver supported by FreeCAD. CalculiX can be downloaded from http://calculix.de

DXF Importer
FreeCAD has a native importer and exporter for DXF files, programmed in C++. Currently this importer does not implement all features of the DXF format. If you rely on a not yet implemented feature, you enable an older python based importer/exporter through by activating the  option. You can then choose to let FreeCAD automatically download the needed files or you can grab them from https://github.com/yorikvanhavre/Draft-dxf-importer. The chosen importer / exporter is used by selecting or  and choosing the  file format.

Elmer
Elmer is a multi-physics simulation software, which was open sourced in 2005. In FreeCAD its Grid and Solver modules can be used by the FEM Workbench through. The project's homepage is at https://www.elmerfem.org and it can be downloaded from GitHub at https://github.com/ElmerCSC/elmerfem/releases.

FEniCS
FEniCS is a computing platform to solve partial differential equations (PDEs), which are widely used when solving FEM problems. As such it can be used by the FEM workbench. FreeCAD can import and export FEniCS meshes through and  by selecting the  file format. The homepage of FEniCS is at https://fenicsproject.org.

GitPython
A python library which is used to interact with Git repositories. The feature is currently in development status in FreeCAD. The Addon Manager can use this library to import addons from a Git repository. The project is hosted on GitHub at https://github.com/gitpython-developers/GitPython.

Gmsh
