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
