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

In my opinion this software is really promising, but from the usability standpoint, it's a piece of garbage. I couldn't create a relatively simple model without stumbling upon bugs every few minutes and the software would crash occasionally too. You create a box, try to fillet two edges it and suddenly it teleports 10cm lower. What the heck? I was really hoping to use Linux for CAD modelling, but it looks like I will have to install Windows just for that. Oh, and the user interface - it is a disaster and I think they couldn't make it any less user friendly.

I love FreeCad!!! The plugin selection is huge, sketch, draft, part .... There is a learning curve, but after you've built a few models it feel natural. This is a project I check twice weekly for updates. If you have a 3D printer I recommend building the parts in FreeCAD.

This is how regular CAD should work: You draw a thing on a flat plane. Then you extrude that thing into the 3rd dimension. This is how FreeCAD works: You multiply delta with Avagadro’s number to get the apple pythagorean theorem. Then you use the apple pythagorean theorem to spaghettify delta with a circular eversion and the X value of a random pixel on the screen. That gives you Graham’s number. You hemispherize the Y value of that pixel from Graham’s number to get the square root of delta consumptionizationified. Consume that number to a random point in spacetime, and you get a cube. Repeat that whole process again to do things to the cube.

Install OFFLINE on BeeFree OS using wizard. Excellent

I had high hopes for FreeCAD. All the tutorial videos looked fantastic, here and there a small glitch, not too much to worry about as the goal was still achieved. My Mac OS X version of FreeCAD is unusable and extremely unstable. My user experience in this environment is sad to say a complete disappointment. I will try the Windows version and have better results to report.
