FreeCAD is a general purpose open source parametric 3D CAD modeler licensed under the LGPL License. FreeCAD is aimed directly at mechanical engineering and product design but, being very generic, also fits in a wider range of uses around engineering, such as architecture, finite element analysis, 3D printing, and other tasks. FreeCAD features tools similar to CATIA, SolidWorks, Solid Edge or Revit, and therefore also falls into the category of CAD, PLM, CAx, CAE and BIM. It is a feature based parametric modeler with a modular software architecture making it possible to provide additional functionality without modifying the core system. As with other CAD modelers it has many 2D components in order to sketch planar shapes or create production drawings. However, direct 2D drawing (like Inkscape or AutoCAD LT) is not the focus, neither are animation or mesh editing (like Blender, Maya, 3ds Max, or Cinema 4D). Nevertheless, thanks to its wide adaptability, FreeCAD is useful in a much broader area around its base feature set. FreeCAD makes heavy use of open-source libraries that exist in the field of scientific computing. Among them are Open Cascade Technology (OCCT), a powerful CAD kernel; Coin3D, a toolkit for 3D graphics development compatible with Open Inventor; Qt, the world-famous user interface framework; and Python, a modern scripting language. FreeCAD itself can also be used as a library by other programs. FreeCAD is also multi-platform, and currently runs on Linux/Unix, Windows, and macOS systems with the same look and functionality on all platforms.
FreeCAD is a free and open-source multiplatform 3D parametric modeler designed to empower users with advanced design capabilities. It offers a comprehensive suite of tools for creating precise and complex models, enabling seamless integration of various design workflows.
Key Features:
- Parametric Modeling: Create and modify designs with constraints-based modeling for flexibility and precision.
- Multiplatform Compatibility: Runs smoothly on Windows, macOS, and Linux, ensuring accessibility across different environments.
- Scripting Interface: Leverage Python scripting to automate tasks and customize functionality, enhancing productivity and adaptability.
Audience & Benefit: Ideal for engineers, architects, product designers, and hobbyists seeking a cost-effective solution. FreeCAD provides the flexibility to handle diverse projects from small-scale creations to large industrial applications, ensuring scalability and versatility in design processes.

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.
On most Linux distributions, FreeCAD is also directly installable from the software center application.
For development releases check the weekly-builds page.
Other options are described at the wiki Download page.
Compiling
Compiling FreeCAD requires installation of several libraries and their development files such as OCCT (Open Cascade), Coin and Qt, listed in the pages below. Once this is done, FreeCAD can be compiled with CMake. On Windows, these libraries are bundled and offered by the FreeCAD team in a convenient package. On Linux, they are usually found in your distribution's repositories, and on macOS and other platforms, you will usually have to compile them yourself.
