FreeCAD is an open-source parametric 3D CAD modeler aimed at mechanical engineering and product design, though it also includes tools for architecture and technical drawing. Being parametric means design changes automatically propagate through a model's history, similar to commercial CAD packages like SolidWorks or Fusion 360. It is organized into "workbenches" — task-specific toolsets for sketching, part design, assembly, simulation and more — and can be scripted and extended with Python.
FreeCAD vs Commercial CAD Software
Commercial parametric CAD tools like SolidWorks and Fusion 360 charge ongoing subscription fees, while FreeCAD offers a comparable parametric modeling workflow at no cost and with the source code fully open. Its workbench system lets you switch between sketching, part design, assembly and simulation tools without leaving the same application.
FreeCAD Features
- Parametric Part Design — build solid models from sketches with fully editable feature history.
- Assembly Workbench — combine multiple parts into constrained assemblies.
- Sketcher — 2D constraint-based sketching used as the basis for 3D features.
- TechDraw — generate 2D technical drawings and dimensioned sheets from 3D models.
- Architecture/BIM Tools — walls, structures and IFC support for building design.
- Python Scripting — automate modeling tasks or build custom workbenches via Python.
- FEM Workbench — basic finite element analysis for stress and other simulations.
- Wide File Format Support — import and export STEP, IGES, STL, DXF and other common CAD formats.

Is FreeCAD really free?
Open Source. FreeCAD is completely free, with its source code released under an open-source license, and can be used for personal, educational or commercial projects at no cost.
How to download FreeCAD safely
Use the request button on this page and we will email you the current link for www.freecad.org — the publisher's own website — so you receive the authentic build. We do not host, mirror, patch or repackage this software in any way.
Avoid third-party "download manager" sites offering FreeCAD. They commonly wrap the genuine installer in their own bundler, which is how adware and browser hijackers get onto a machine that the user believed was clean.
