FreeCAD
a parametric 3D CAD modeler
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. -

LeoCAD
A CAD application for creating virtual LEGO models
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. -

CADAM
CADAM is the open source text-to-CAD web application
CADAM is an open-source “text-to-CAD” web application that turns natural-language prompts into parametric 3D models, targeting a workflow where you describe what you want and the system produces editable geometry. It is designed around a browser-first experience, so users can iterate quickly without installing a heavyweight desktop CAD suite for every experiment. A key idea is that the generated output is parametric and scriptable, enabling repeatable edits and variations rather than a one-off mesh result. The project integrates modern web tooling and a backend stack to manage sessions, model generation requests, and persisted outputs, making it usable as an actual product rather than only a demo. It’s also built to support an agentic workflow, where the system can refine outputs over multiple steps, bridging the gap between intent (“a bracket with four mounting holes”) and precise geometry. -

jEPlus - Parametrics for E+ and TRNSYS
An EnergyPlus shell for parametric studies and more ...
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
A math-inspired CAD program in haskell. CSG, bevels, and shells
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. -

The 1-dimensional gas-dynamics code. More information in http://www.openwam.com Modeling is an important technique for the optimization of internal combustion engines (ICE). The use of calculation models together with experimental tests is producing unquestionable successes due to the fact that both techniques complement each other. 1D wave action models simplify the engine by means of ducts, where only one dimension is considered, and volumes where mass accumulation is considered and the gas properties are uniform in the entire element. Finally, non dimensional models are used to solve connections between 1D and 0D elements. Thanks to more than 20 years, more than 10 PhD Thesis and many research projects and publications, CMT-Motores Térmicos has developed an own 1D gasdynamic tool called OpenWAMTM which gathers an important know-how on air management, compressible flow, turbocharging, chemical species tracking, numerical analysis and many other aspects of engine modeling.
