Overview
--------

* **Freedom to build what you want**  FreeCAD is an open-source parametric 3D 
modeler made primarily to design real-life objects of any size. 
Parametric modeling allows you to easily modify your design by going back into 
your model history to change its parameters.

* **Create 3D from 2D and back** FreeCAD lets you to sketch geometry constrained
 2D shapes and use them as a base to build other objects. 
 It contains many components to adjust dimensions or extract design details from 
 3D models to create high quality production-ready drawings.

* **Designed for your needs** FreeCAD is designed to fit a wide range of uses
including product design, mechanical engineering and architecture,
whether you are a hobbyist, programmer, experienced CAD user, student or teacher.

* **Cross platform** FreeCAD runs on Windows, macOS and Linux operating systems.

* **Underlying technology**
    * **OpenCASCADE** A powerful geometry kernel, the most important component of FreeCAD
    * **Coin3D library** Open Inventor-compliant 3D scene representation model
    * **Python** FreeCAD offers a broad Python API
    * **Qt** Graphical user interface built with Qt

Installing
----------

Precompiled packages for stable releases are available for Windows, macOS and Linux on the
[Releases page](https://github.com/FreeCAD/FreeCAD/releases).

On most Linux distributions, FreeCAD is also directly installable from the 
software center application.

For development releases visit the [weekly-builds page](https://github.com/FreeCAD/FreeCAD-Bundle/releases/tag/weekly-builds).

Other options are described on the [wiki Download page](https://wiki.freecad.org/Download).

Compiling
---------

FreeCAD requires several dependencies to correctly compile for development and
production builds. The following pages contain updated build instructions for
their respective platforms:

- [Linux](https://wiki.freecad.org/Compile_on_Linux)
- [Windows](https://wiki.freecad.org/Compile_on_Windows)
- [macOS](https://wiki.freecad.org/Compile_on_MacOS)
- [MinGW](https://wiki.freecad.org/Compile_on_MinGW)

Reporting Issues
---------

To report an issue please:

- Consider posting to the [Forum](https://forum.freecad.org), [Discord](https://discord.com/invite/F4hdxzYZfc) channel, or [Reddit](https://www.reddit.com/r/FreeCAD) to verify the issue; 
- Search the existing [issues](https://github.com/FreeCAD/FreeCAD/issues) for potential duplicates; 
- Use the most updated stable or [development versions](https://github.com/FreeCAD/FreeCAD-Bundle/releases/tag/weekly-builds) of FreeCAD; 
- Post version info from `Help > About FreeCAD > Copy to clipboard`; 
- Restart FreeCAD in safe mode `Help > Restart in safe mode` and try to reproduce the issue again. If the issue is resolved it can be fixed by deleting the FreeCAD config files.
- Start recording a macro `Macro > Macro recording...` and repeat all steps. Stop recording after the issue occurs and upload the saved macro or copy the macro code in the issue; 
- Post a Step-By-Step explanation on how to recreate the issue; 
- Upload an example file (FCStd as ZIP file) to demonstrate the problem;
