Jul 21, 2019 The FreeCAD Gui suddenly became a Parametric Designer. It is rare to run across a simple solution that changes the landscape as much as this one. FreeCAD is designed for parametric modeling. This means that the geometry that you create, instead of being freely sculptable, is produced by rules and parameters. For example, a cylinder might be produced from a radius and a height. With these two parameters, the program has enough information to build the cylinder.
FreeCAD is a general purpose parametric 3D CAD modeler. The development is completely Open Source (LGPL License). FreeCAD is aimed directly at mechanical engineering and product design but also fits in a wider range of uses around engineering, such as architecture or other engineering specialties.
FreeCAD features tools similar to Catia, SolidWorks or Solid Edge, and therefore also falls into the category of MCAD, PLM, CAx and CAE. Voxal voice changer anonymous. It is a feature based parametric modeler with a modular software architecture which makes it easy to provide additional functionality without modifying the core system.
As with many modern 3D CAD modelers it has many 2D components in order to sketch 2D shapes or extract design detail from the 3D model to create 2D production drawings, but direct 2D drawing (like AutoCAD LT) is not the focus, neither are animation or organic shapes (like Maya, 3ds Max, Blender or Cinema 4D), although, thanks to its wide adaptability, FreeCAD might become useful in a much broader area than its current focus.
Parametric Design Architecture
FreeCAD makes heavy use of all the great open-source libraries that exist out there in the field of Scientific Computing. Among them are OpenCascade, a powerful CAD kernel, Coin3D, an incarnation of Open Inventor, Qt, the world-famous UI framework, and Python, one of the best scripting languages available. FreeCAD itself can also be used as a library by other programs.
FreeCAD is also fully multi-platform, and currently runs flawlessly on Windows and Linux/Unix and Mac OSX systems, with the exact same look and functionality on all platforms.
* FreeCAD download link provides gnu general public license version of the software for Windows 32bit, Windows 64bit, Mac and Linux.

FreeCAD - though usable in many applications - is at the beginning of a long journey into CAD mainstream. There is still a lot to do to reach a state where we can compete with commercial software.
This section gives an overview of what is planned and gives you the opportunity to participate or give your opinion. As we are volunteers to FreeCAD we have only a certain amount of time. So if you interested in one of the topics and willing to help, just let us know! We use the Getting Things Done (GTD) style for the project document. Here is the Project template.

Release schedule
Like in the most FLOSS projects a release schedule is very rough. There will be no fixed dates and 'It's done, when it's done!'
