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.

Open Source CAM - Toolpath Generation for 3-Axis CNC machining

An STL format importer/exporter plugin script for Google SketchUp. Supports both binary and ASCII import and export.

This is the Link branch FreeCAD, with lots of new features and enhancements. This branch is originally created to develop the App::Link feature for use with my Assembly3 workbench. The feature has since been merged with official FreeCAD, but the branch stayed and became the forefront of what future FreeCAD might become. Its function now is to continuously improve and test the Topological naming problem and its fix. Which I eventually plan to merge back into the FreeCAD main branch.

FRAME3DD is a program for the static and dynamic structural analysis of two- and three-dimensional frames and trusses with elastic and geometric stiffness.

conducteö est un logiciel de modélisation et de simulation des ponts thermiques linéiques, conforme à la RT 2012 et aux principales normes européennes concernant les ponts thermiques.

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.

The count of vehicles is a key task in traffic gauging, as it provides information for designing new roads. This software presents an algorithm to detect and track vehicles in real time or from a video file.

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/

ImplicitCAD is a programmatic CAD program, implemented in Haskell. Unlike traditional CAD programs, programmatic CAD programs use text descriptions of objects, as in programming. Concepts like variables, control structures and abstraction are used, just as in programming. With the explosion of 3D printing, designing 3D objects has become an even more important problem. And it's a complicated one. We need to design complicated objects that precisely interface with each other. And often we don't want to just design a single object, but classes of objects, parameterized by variables. And we need to do this in collaboration. Generally, objects in programmatic CAD are built with Constructive Solid Geometry or CSG. Unions, intersections and differences of simpler shapes slowly build the object. ImplicitCAD supports all this and much more! For example, it provides rounded unions so that one can have smooth interfaces between objects.

Design virtual models you can build with LEGO® bricks. LeoCAD has an intuitive interface that is designed to allow new users to start creating new models without having to spend too much time learning the application. At the same time, it has a rich feature set that enables experienced users to build models by using techniques that are more advanced. LeoCAD is fully compatible with the LDraw Standard and related tools, and it reads and writes LDR and MPD files so that you can share and download models from the Internet. It also uses the LDraw parts library, which has over 10,000 different parts and continues to receive updates. Native versions are available for Windows, Linux, and macOS to ensure that users are familiar with the program interface. LeoCAD is open-source, so anyone can contribute with fixes and features, and it is always going to remain free.

A python gear generator that serves as CAE/CAD-preprocessor for involute gears based on pythonOCC. It allows for the computation of dynamic properties and the creation of exact geometries from a minimal input set. PyGear can simulate the tool geometry and kinematics of standard gear hobbing tools to generate precise flank, tooth root and tip geometries. Disclosure: the software is open-source and free to use thanks to support received from http://smithbot.com, the easy-to-use AI crypto bot trading platform.
