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.
- 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
It's an excellent software. It still lacks: - assembly management - FEM support for Code ASTER (open source certified engineering sofrware). There's just Calculix support :-( - structured mesh support (it's needed for FEM model patch test) - spline in sketch
Powerful and lightweight program. Easy to use.
FreeCAD is the CAD software of the future from mechanical to architecture work. But you know the future is now. FreeCAD est le logiciel de CAO du futur pour travailler depuis la mecanique jusqu'à l'architecture. Mais vous savez que le futur c'est maintenant.
FreeCAD is a powerful open source (LGPL license) parametric 3D CAD program. It is still under development, and version 0.14 was recently released. FreeCAD has an active web forum too. See the Users Showcase area to see some of what has been done with FreeCAD. There are also forum areas for those people who may have trouble installing FreeCAD, and another area for people who need help using FreeCAD. I have some YouTube video tutorials under the user name bejant000 that are intended to help new users learn FreeCAD to make 3D models. I've been using FreeCAD for just over a year (so yeah, I'm biased) and thought I'd post this info to help new FreeCAD users.
FreeCad is very good. There is another free CAD project: sourceforge.net/projects/cadplatform/
