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 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
[latest releases page](https://github.com/FreeCAD/FreeCAD/releases/latest).
On most Linux distributions, FreeCAD is also directly installable from the
software center application.
For weekly development releases visit the [releases page](https://github.com/FreeCAD/FreeCAD/releases/).
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)

Reporting Issues
---------
To report an issue please:
- Consider posting to the [Forum](https://forum.freecad.org), [Discord](https://discord.com/invite/w2cTKGzccC) 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/releases/) 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;
