Overview

FreeCAD Free Download – Open-Source 3D CAD Software

FreeCAD is a free and open-source parametric 3D CAD (Computer-Aided Design) modeler. It is designed for product design, mechanical engineering, and architecture, offering a full range of professional CAD tools. This article provides a comprehensive guide to downloading, installing, and using FreeCAD.

What is FreeCAD?

FreeCAD is an open-source parametric 3D modeler that is suitable for designing real-life objects of any size. It is available for Windows, macOS, and Linux, and is distributed under the GNU General Public License. The current stable version is 1.1.1, released in April 2026.

FreeCAD is designed for parametric modeling, meaning that changes to the model's parameters automatically update the entire design. This makes it ideal for engineering and product design workflows where designs need to be iterated and refined. FreeCAD is completely free and open-source, with no limitations on its use for personal or commercial projects.

Key Features of FreeCAD

Parametric Modeling

FreeCAD uses a parametric modeling approach where the model is built from a history of operations. Changing any parameter automatically updates the entire model.

Multi-Platform

FreeCAD runs on Windows, macOS, and Linux with consistent features across all platforms.

Architecture and BIM Tools

FreeCAD includes specialized tools for architecture and Building Information Modeling (BIM), making it suitable for architectural design.

Mechanical Engineering

Tools for mechanical engineering include part design, assembly, and finite element analysis (FEA) capabilities.

Scripting and Customization

FreeCAD can be extended and automated using Python scripting, allowing users to create custom tools and workflows.

How to Download FreeCAD

FreeCAD can be downloaded from the official website at freecad.org.
