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
TexGen is a geometric textile modelling software package to be used for obtaining engineering properties of woven textiles and textile composites.
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)
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
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.
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.
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.
An easy and flexible mathematical programming environment for Python.
PyMathProg is a Python reincarnation of AMPL and GNU MathProg modeling language, implemented in pure Python, connecting to GLPK via swiglpk. Create, optimize, report, change and re-optimize your model with Python, easily integrate database, plotting, etc.

Linux tiny CAD for educational purposes
Linux TinyCad, or LiniCad, is a tiny CAD used for educational purposes. It is written in Python/Tk and its goals are to be as programmatically easy and small as possible.
ThanCad is a 2dimensional cad, with limited 3d support and raster inclusion capability and emphasis in engineering. It is being written in Python and since it uses the Tkinter library, it is platform independent.
Open Source FabLab Project
Software script assembly to be executed on cnc machines and robots to build, maintain and replicate open source fablab. Here software meets hardware.
This application is intended to be a tool for easy, almost automatic, creation and calculation of gear transmission finite element models. It consists of a geometry and mesh generator based on GMSH and a finite element model based on GETFEM++.
2D Frame Analysis, Linear Static Analysis, Mode Shapes
This is a free program for solving linear 2D framed structures under static loading and calculating the mode shapes. It is coupled with an easy-to-use GUI that provides the possibility to design the structure very fast. It calculates reaction forces, diagrams of axial and shear forces, as well as, diagrams of bending moments. Moreover, it calculates the mode shapes of the structure using various methods and it will be cabable of performing dynamic analysis soon. The program is written in FORTRAN90 and the GUI in Python. At the moment it is available only in 64bit version for windows.
Simple CAM program for creating RS274NGC gcode from vector format files like DXF CF2 PLT. Can be used with AXIS interface from EMC project. It's early alpha stage.
The BladeDesigner package is a CAD/CAE tool providing classes for turbomachine blade design. So far it is optimized to be useful in the aerodynamic design process. It comes with a GUI but is most powerful with user defined python scripts.
CNC control software
Программа обеспечивает импорт разных форматов файлов и обработку по ним на станке ЧПУ.
Simple CAD program
SAMoCAD - its program to create simple drawings, partially supports DXF. Main features: - create simple objects (line, arc, circle) - create complex objects (text, dimensions) - edit drawn objects - save drawing to SVG format - output drawing in PostScript format - export/import content DXF files (primitives LINE, CIRCLE, ARC, TEXT, DIMENSION) Program written in Python 2 and use the library Tkinter. Program requires no installation, but you need install Python 2.7 or later on your PC. Run file SAMoCAD.pyw to run the program. Its very old version of program!!! For more information see
A designer’s program for describing parts of the building
Buildes is an integrated development environment that assists the user in creating building information. It reads a text (session) file from which it compiles the information. It then allows the user to browse, analyze and export the resulting building knowledge. The compilation system is written in pure Python. The building components created are rendered in PythonOCC. The GUI is written using PyQt.
This plugin exports G-Code for a wirecutter
The "wirecutter" plugin for inkscape is a plugin to generate g-Code for a 2D wirecutter with a turning table. You can either draw one open path which is the path which the machine will cut or you can draw some closed paths. These closed paths (e.g. Letters) must be connected because the cutter cannot leave the raw material like a milling machine. The Plugin helps you to create these connectors. If you have a wirecutter with a turning table you can create multiple "cuts" for different positions of the turning table. This software is not really tested and is still in development.
EMTG is NASA Goddard's autonomous space mission design tool.
Warning, EMTGv8 is no longer supported by NASA GSFC. Furthermore, we are no longer able to supply a binary version. However, if anyone wants to use the source code for EMTGv8 and compile it yourself against a recent available SNOPT, we wish you the best. This will require some C++ programming skills and the ability to work with a complex build system. Some day in the future we hope to release EMTGv9 open-source, but for a variety of reasons it is not possible to do that right now.
