This is an official mirror of FreeCAD. Code and release files are primarily hosted on https://github.com/FreeCAD/FreeCAD and mirrored 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.

A Windows only 2.5D CAD CAM application. The user experience tightly integrates the CAM aspects when doing design and layout. The target users will layout their design and then immediately generate CNC code. The goal is a design application closer to Adobe Illustrator than to AutoCAD. The user specifies machining aspects during object creation so that when the design/layout phase is completed the toolpath generation can occur automatically. What is 2.5D? Objects created are flat (2D) but have a depth component. So you can create a square that will be machined at a specific depth but the depth will be constant accross the square. It is not/does not: A general purpose CAD (AutoCAD) type program. Support reference dimension on the drawing. Export or import major CAD file formats.

Impact is an explicit Finite Element Program Suite which simulates dynamic impact events. It has a range of elements, contact handling and different material laws. Models can be created, solved and analyzed with the included pre- and postprocessor. Impact is based on an Explicit Time stepping algorithm. These kind of codes are used to simulate dynamic phenomena such as car crashes and similar, usually involving large deformations.

Libre Mechanics it’s an Open Knowledge project created to offer a useful platform of information related with the development and research of Mechanical Engineering themes and similar fields, higly related with the use of Open Source and Software Libre tools. Here you will find a wide variety of projects, publications and scientific material available as references for developing their own projects, also guides and tutorials that allow you to take advantage of free software tools available today. The four principal lines of work are: Design Analysis and Simulation Automation and Robotics Development

Parametric analysis is often needed for exploring design options, especially when a global optimization method is not available, or the optimization result is in doubt. Parametric analysis can also be applied to all design variables simultaneously, which forms an exhaustive search that, providing that the search grid is fine enough, will guarantee a global optimum solution. In order to perform complex parametric analyses on multiple parameters with more than a handful of alternative values each, a tool to generate commands for the simulation model to run, and to collect results afterwards will be needed. jEPlus has been developed as such a parametric tool for EnergyPlus. To see jEPlus in action, check out this video: http://youtu.be/jBA7Q7npNK4 The source code of the jEPlus project is now hosted on GitHub: https://github.com/jeplus/jEPlus/

PotterDraw is a free 3D software application for designing and visualizing pottery. It’s useful for creating cylindrical shapes such as pots, flasks, vases, bowls, plates, cups, glasses, goblets, or anything similar. The outer wall of the pot is drawn using a spline, which consists of one or more curved or linear segments. The inner wall is generated automatically. PotterDraw can export files suitable for 3D printing. It can also map synthesized or user-specified textures onto the pot. Mesh and texture properties can be modulated by oscillators for more complex effects, and the modulations can be animated to create videos.
