WARNING: FreeCAD has moved!

FreeCAD code and release files are now hosted on github at https://github.com/FreeCAD/FreeCAD

Only older files and code are available here.

FreeCAD is a general purpose feature-based, parametric 3D modeler for CAD, MCAD, CAx, CAE and PLM, aimed directly at mechanical engineering and product design but also fits a wider range of uses in engineering, such as architecture or other engineering specialties. It is 100% Open Source and extremely modular, allowing for very advanced extension and customization.

FreeCAD is based on OpenCasCade, a powerful geometry kernel, features an Open Inventor-compliant 3D scene representation model provided by the Coin 3D library, and a broad Python API. The interface is built with Qt. FreeCAD runs exactly the same way on Windows, Mac OSX and Linux platforms.

Features

  • Rock-solid OpenCasCade-based geometry kernel, allowing complex 3D operations on complex shape types, and supports natively concepts like brep, nurbs, booleans operations or fillets
  • Full parametric model allowing any type of parameter-driven custom objects, that can even be fully programmed in python
  • Complete access from python built-in interpreter, macros or external scripts to almost any part of FreeCAD, being geometry creation and transformation, the 2D or 3D representation of that geometry (scenegraph) or even the FreeCAD interface

User Reviews

  • Cool program - but the interface is terrible. It requires a tutorial just to find basic tools - and the measurement tool does not show unit type, so when I imported a file and finally found the measurement tool is just told me it was 664 long.
