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

• Create 3D from 2D and back FreeCAD lets you to sketch geometry constrained2D shapes and use them as a base to build other objects.It contains many components to adjust dimensions or extract design details from3D models to create high quality production-ready drawings.

• Designed for your needs FreeCAD is designed to fit a wide range of usesincluding 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
