About

What is FreeCAD?

FreeCAD is a powerful, open-source parametric 3D modeler built for designing real-life objects across various domains like product design, mechanical engineering, and architecture. It enables users to easily modify designs by leveraging its parametric modeling capabilities, allowing changes to parameters within the model history. The software supports creating 3D objects from constrained 2D shapes and extracting design details to produce high-quality, production-ready drawings. FreeCAD is multiplatform (Windows, Mac, Linux), highly customizable, and extensible, supporting numerous open file formats for seamless integration into diverse workflows. It offers advanced features like Finite Element Analysis (FEA), experimental CFD, BIM, Geodata, CAM/CNC workbenches, and a robot simulation module, making it a versatile engineering toolkit.
