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
