Choisissez votre système d'exploitation
FreeCAD est une application véritablement multi-plateforme, développée avec Qt de renommée mondiale.

Qu'est-ce que cela signifie, c'est que FreeCAD ressemble et agit de la même façon sur Windows, Linux et Mac. Toutefois, la procédure d'installation est un peu différente pour chaque système d'exploitation.

Choisissez votre système d'exploitation ci-dessous, pour avoir plus de détails sur la façon d'installer FreeCAD.

Installation du contenu supplémentaire
La documentation hors-ligne n'est pas fournie avec toutes les méthodes d'installation, et est donc disponible séparément. Consultez la page Installer d'un fichier d'aide.

En plus des ateliers livrés par défaut avec FreeCAD, il existe une collection grandissante d'ateliers et de modules additionnels produits par des membres de la communauté et disponibles sur le Web. Plusieurs initiatives (listées ci-dessous) sont en cours pour les rassembler et les rendre disponibles de façon conviviale.

Puisque ces ateliers ne font pas partie de la version officielle de FreeCAD, et qu'ils ne sont pas supportés par l'équipe de développement, vous devriez lire l'information fournie dans chacune des pages de greffons avant de les installer, afin de savoir ce que vous installez. De plus, les rapports de bogues et les demandes de fonctionnalité devraient être adressés aux page de greffons.

Le dépôt FreeCAD-addons
Il s'agit d'un regroupement d'atelier utiles, utilisant le système de sous-modules Git, ce qui permet la mise à jour constante du contenu. Le dépôt FreeCAD-addons se trouve sur ce lien : https://github.com/FreeCAD/FreeCAD-addons. Ce dépôt propose une macro d'installation qui peut être lancée depuis FreeCAD ; celle-ci liste, télécharge et installe les greffons sélectionnés automatiquement. Pour installer la macro :

With older version of FreeCAD, to install the installer macro:


 * 1) Faire un clic droit sur addons_installer.FCMacro puis sélectionner « Enregistrer la cible du lien sous... »
 * 2) Sauvegarder la macro téléchargée dans votre dossier de macros FreeCAD. L'emplacement du dossier de macros est indiqué dans le menu Macros -> Macros... -> Emplacement des macros de l'utilisateur :
 * 1) Redémarrer FreeCAD. La macro addons_installer sera listée dans le menu Macros -> Macros... et pourra être lancée en la sélectionnant puis en cliquant sur le bouton Lancer :

Le greffon pluginloader
Le greffon pluginloader (chargeur de greffons) est une méthode beaucoup plus élaborée d'installer et gérer le contenu additionnel dans FreeCAD. Installez-le selon la même méthode que pour le dépôt FreeCAD-addons, ou suivez les instructions (en anglais) sur la page pluginloader.

Installation manuelle
Les ateliers externes, quand ils sont pleinement programmés en langage python (ce qui est le cas de tous les ateliers actuels au moment d'écrire ces lignes) peuvent être aisément installés manuellement, simplement en les téléchargeant (habituellement en cliquant sur le bouton **Download ZIP** apparaissant sur la page de chacun des greffons quand ils sont hébergés sur GitHub), puis en les plaçant dans votre dossier FreeCAD/Mod (ou dans le dossier Macros s'il s'agit de macros). Reportez-vous aux instructions de chaque page greffon pour des instructions complètes.

Notes pour les utilisateur du système 32-bit et FreeCAD 0.16.6712
Aprés installation, des Workbenches additionnels ne sont accessibles. Dans ce cas
 * Ouvrir la fenètre de Rapport aprés ouverture FreeCAD, et lire l'erreur

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. One, CalculiX GraphiX, or calculix-cgx, is a GUI frontend to display the results of the second package, CalculiX CrunchiX, or calculix-ccx, a FEM solver. Only the latter one 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 multiphysical simulation software, which was open sourced in 2005. In FreeCAD its Grid and Solver modules can be used by the FEM workbench through. The projects 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
