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.
On most Linux distributions, FreeCAD is also directly installable from the software center application.
For weekly development releases visit the releases page.
Other options are described on the wiki Download page.
Compiling
FreeCAD requires several dependencies to correctly compile for development and production builds. The following pages contain updated build instructions for their respective platforms:
Reporting Issues
To report an issue please:
- Consider posting to the Forum, Discord channel, or Reddit to verify the issue;
- Search the existing issues for potential duplicates;
- Use the most updated stable or development versions of FreeCAD;
- Post version info from
Help > About FreeCAD > Copy to clipboard; - Restart FreeCAD in safe mode
Help > Restart in safe modeand 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;
