a parametric 3D CAD modeler
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.

DXF2GCODE: converting 2D dxf drawings to CNC machine compatible G-Code
DXF2GCODE is a tool for converting 2D (dxf, pdf, ps) drawings to CNC machine compatible GCode. Windows, Linux, and Mac support by using python scripting language.
Open Source CAM - Toolpath Generation for 3-Axis CNC machining
A graphical tool to design a bicycle (s) geometry and derive drawings from its configuration
An STL format importer/exporter plugin script for Google SketchUp. Supports both binary and ASCII import and export.
This small program can help you to calculate optimal cut of rectangular details. It can be used to design cutting out of wood, glass, steel and other material.
Static and Dynamic Structural Analysis of 2D and 3D frames.
FRAME3DD is a program for the static and dynamic structural analysis of two- and three-dimensional frames and trusses with elastic and geometric stiffness.
Simple CAD program
ZCAD is simple CAD program with dxf2000 file format support. Source code available here http://svn.shamangrad.net/zcad/trunk/
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.
Software for electromagnetic simulation
MaxFem is an open software package for electromagnetic simulation by using finite element methods. The package can solve problems in electrostatics, direct current, magnetostatics and eddy-currents. We have moved the installers to the MaxFEM website (see below). In order to improve MaxFEM, we will require you to fill out a simple form before downloading them.
PythonCAD is a CAD package written, surprisingly enough, in Python using the PyQt interface. The PythonCAD project aims to produce a scriptable, open-source, easy to use CAD package for Linux (Cross Platforms)
TexGen is a geometric textile modelling software package to be used for obtaining engineering properties of woven textiles and textile composites.
2.5D CAD CAM emphasis on CAM and toolpaths
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.
Open-Source Multiphysics FEA (FEM) Package
CalculiX Binaries for MS Windows, made with CYGWIN and ARPACK libraries. CalculiX is most popular FEA open-source package (like Code-Aster and Elmer-FEM). it is comparable in features with most known commercial packages like ANSYS, NASTRAN, Abaqus, etc. Good for structural, mechanical, thermal and fluid applications (trusses, plates, frames, shells, solid bodies). It has powerful nonlinear capabilities (including tension/compression only material like concrete) and most types of analysis (modal, thermal, buckling, coupled, etc) . See home page at http://www.dhondt.de New versions can be obtauned here: http://calculixforwin.blogspot.com/2015/05/calculix-launcher.html
CNC code generator is a software to generate CNC codes (G & M codes) for maching operations like milling, drilling. At present CNC code generator is limited for end milling. we working on other machining operations like turning, drilling etc.
A Simple 2D CAD/CAM application (currently Windows-only) Cuts simple shapes (pockets, mostly) and simplified gears. It has a geometry mode that allows geometry defined by lines and arcs. It also generates geometry from any OpenType-style font!
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.
Our primary goal is to create a great, full featured, 3D CAD environment for Blender for use by engineers, designers, drafters, architects, etc. based on the OpenCascade toolkit.
A small program to quickly generate g-code. It can generate circular pockets, square pockets, etc. Now you can generate a simple program from DXF. Use the tab "Cutting a path" or "Array of elements". Added engraving by DXF file.
Open Knowledge on engineering development.
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
