FreeCAD Installer
Für Windows (XP, Vista und 7, 32 und 64bits),  Mac OS X (Lion 10.7 64bit) und  Debian-basierte Linux Systeme (Debian, Ubuntu LTS und aktuell, 32 und 64bit) werden installationsfertige Pakete angeboten. Untenstehen finden Sie die Links für die stabilen Versionen der verschiedenen Systeme. Ebenso sind unter FreeCAD Files page die instabilen Pakete verfügbar, die die allerneuesten Funktionen zur Verfügung stellen, an denen gerade gearbeitet wird. Diese könnten jedoch öfter abstürzen oder Funktionen enthalten, die mit früheren Versionen inkompatibel sind.

Entwicklerversionen
Wenn Sie FreeCAD Enticklungsversionen installieren möchten und bereit sind, häufigere Fehler und Abstürze zu akzeptieren, dann können Sie unter FreeCAD Files page 64bit, ältere oder instabile Versionen herunterladen. Wenn Sie jedoch noch näher and die aktuelle Entwicklung rücken möchten, können Sie FreeCAD selbst kompilieren, das Archiv Ubuntu daily build updates verwenden oder eine der Vorversionen auf der Github Seite verwenden.

Hinweise für Windows-Anwender
Der Windows Installer sollte auch auf älteren Windows-Plattformen funktionieren, obwohl er nicht auf allen Plattformen getestet wurde. Sie müssen mindestens Windows Installer V1(msiexec.exe) auf Ihrem System installiert haben. Siehe Installieren auf Windows für weitere Details über die verschiedenen Installationsmöglichkeiten. Laden Sie die neueste .msi-Datei für Windows-Systeme, oder die entsprechende .deb-Datei für Ihre Version von Ubuntu oder Debian herunter.

Hinweise für Linux-Anwender
Bei den neusten Version von bekannten Linux-Distrubutionen wie Debian, Ubuntu oder Arch ist FreeCAD bereits in den offiziellen Distributions-Paket-Repositories enthalten. Es ist zu Empfehlen, FreeCAD vorzugsweise von dort zu beziehen, um sicherzustellen, dass Sie eine zu Ihrem System 100%-kompatible Version erhalten. FreeCAD benötigt auch das pivy-Python-Modul (in der Regel mit dem Namen python-pivy) ab Version 0.9 oder höher. Wenn es nicht auf Ihrem System vorhanden ist, müssen Sie es ebenfalls dort herunterladen.

Notes for Debian users
Because of a licensing conflict between third-party libraries required by FreeCAD, the freecad package was removed from the current Debian stable (wheezy) repository. This will be solved when the next stable release of FreeCAD comes out. In the meanwhile, you can either compile FreeCAD or use an alternate build.

You should also note that although Ubuntu is based on Debian, the Ubuntu PPA packages are NOT compatible with Debian.

Notes for Mac users
We rely on very few people to help building Mac OSX packages, so it doesn't get updated as often as the other platforms. The version available on this site might be slightly outdated. (To compile the most up-to-date version from source see CompileOnMac)

You can follow the topic dedicate to Mac on the forum

Ubuntu PPA Pakete
Das FreeCAD Launchpad team hat ein automatisches Build-System aufgebaut, das tagesaktuelle Versionen von FreeCAD für Sie bereitstellt. Aktualisierungen der Software werden automatisch im Ubuntu-Update-Manager angezeigt. Der einfachste Weg, um die neuste Version von FreeCAD zu bekommen.

The FreeCAD Daily Builds PPA is an automatic daily build system, which can provide you with a fresh, daily-up-to-date version of FreeCAD. Please be advised that although the packages from this bleeding edge PPA may be broken from time to time, they will likely contain numerous bug fixes and feature updates.

Current supported architectures and versions are:
 * Ubuntu 12.04 LTS (Precise Pangolin) 32 & 64-Bit
 * Ubuntu 14.04 (Trusty Tahr) 32 & 64-Bit
 * Ubuntu 14.10 (Utopic Unicorn) 32 & 64-Bit
 * Ubuntu 15.04 (Vivid Vervet) 32 & 64-Bit
 * Ubuntu 15.10 32 & 64-Bit
 * Ubuntu 16.04 32 & 64-Bit

Adding the PPA and installing FreeCAD from the console
Type (or copy-paste) these commands in a console to add the PPA and install FreeCAD along with the documentation:

Then:

Adding the PPA and installing FreeCAD from the GUI
Add to your system's Software Sources the following PPA (read What are PPAs and how do I use them? if you don't know how):

When a dialog window asks you to refresh your software sources, click OK.

Now you can install FreeCAD and FreeCAD documentation through the Ubuntu Software Center, or your package manager of choice.

Fedora package
To install FreeCAD on Fedora, make sure you have the *NONFREE* repositories installed (necessary because of OCC/OCE license)

Or use the GUI installer.

Alternative FreeCAD builds
These are versions of FreeCAD built by other persons and not officially maintained by the FreeCAD team. They may include customized parts or be optimized for certain types of processors, or other modifications that the package maintainers judged necessary. They might also be out-of-date, since the people who make those package may take time to grab the newer versions of FreeCAD. But they are also sometimes better suited for certain operating systems. Note that on most common linux distributions, official packages are typically installed by the system's package management tool, so you don't need to download and install FreeCAD manually.


 * Official Debian package
 * Official Ubuntu package
 * Official OpenSuse package
 * Softpedia Windows build
 * Packman RPM package (for opensuse, fedora)
 * Slackbuilds package (for Slackware)
 * ArchLinux AUR package
 * Gentoo ebuild package
 * Pardus linux build script
 * Unofficial but well maintained Fedora FreeCAD repository
 * Unofficial Debian Wheezy package (32-Bit and 64-Bit)

FreeCAD documentation
The user documentation of FreeCAD is being written together by the developers and the users community, on this wiki site. The best way is to read it online, so you are sure to get the latest version:
 * The FreeCAD Manual

The manual can also be displayed as one big text, so you can print it or save it as a pdf file:
 * All-in-one printable version

The manual is also be compiled as a qt help file, so it can be browsed offline with the Qt help viewer. This is usually made at each release and is available together with FreeCAD package on most linux software repositories (on debian/ubuntu-based systems, look for freecad-doc package) and is also bundled in the windows installer. To access it, simply open the "help" menu inside FreeCAD, or use the "What's this?" button.

For convenience, with each release we also provide a pdf version of this manual:
 * https://github.com/FreeCAD/FreeCAD/releases

In this Documentation-Directory on Sourceforge you will also find Quick Reference Cards as PDF. They list the pre-defined keyboard-shortcuts for the different workbenches.

Here you can also find a copy of the OpenCasCade 5.2 docs, in a .chm file. After 5.2, the openCasCade documentation is not available as a single file anymore, but as a heavy 180Mb package. So, since there is little change, we keep this one around for convenience:
 * OpenCasCADE 5.2 documentation

FreeCAD Source package
For all other platforms you need to compile FreeCAD on your own from the Source package. You might also want to compile FreeCAD yourself if you want to optimize certain things, or customize certain parts of FreeCAD. Instructions for compiling can be found on the CompileOnWindows, CompileOnMac and CompileOnUnix pages. You can grab a zip or tar.gz file containing the latest official version here (look for the latest version for your system):
 * official FreeCAD Files repository

Alternatively, you can also download latest source code from the Git repositories. You'll get a more recent version, but it might contain bugs or even fail to compile. Instructions for accessing the Git repositories can be found here:
 * FreeCAD Git repository on github

You can also download automatically a GNU tarball from the latest source code tree or any part of it by using the code browser and clicking the "Download GNU tarball" at any time. The trunk folder contains the current development version, while the branches folder contains a snapshot of all stable releases to date.

FreeCAD LibPack
To collect all the needed libraries to compile FreeCAD can be a time consuming task. So we deliver a convenient package for development on Windows (VC8, VC11, and VC12) with all needed libraries. You can download the latest version of the libpack from:
 * FreeCAD LibPackDownload the version that matches your architecture and Visual C++ version.

For linux, you will normally find all necessary libraries in your software management system, so you should just read the CompileOnUnix page.
