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. -

PRTG Catches Network Issues Before They Cause DowntimeReactive troubleshooting usually means hearing about a problem from frustrated users, not your monitoring tool. PRTG sets threshold-based alerts across devices, servers and applications, notifying your team by email, SMS or push the moment a metric crosses a set limit. That means catching a failing disk or overloaded server before it becomes an outage and getting time back from firefighting. Start a free trial and set your first alerts today.

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. -

Open Source Text to CAD Harness
An open source harness for generating CAD models
Open Source Text to CAD Harness is an open-source framework that enables the generation of parametric 3D CAD models using natural language prompts interpreted by AI coding agents. It acts as a harness that converts text descriptions into source-controlled CAD scripts, which are then compiled into geometric models using tools like OpenCascade and build123d. The system emphasizes reproducibility by storing CAD logic as editable code rather than opaque binary files, allowing iterative refinement through agent-driven workflows. It includes a local visualization interface called CAD Explorer for inspecting generated geometry and supports multiple export formats for engineering and manufacturing use. The project also integrates modular “skills” for robotics, motion planning, and manufacturing validation, making it highly extensible. Designed to run locally without backend dependencies, it provides a flexible environment for experimentation and production workflows. -

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.
