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. -
AI-generated apps that pass security reviewRetool lets you generate dashboards, admin panels, and workflows directly on your data. Type something like “Build me a revenue dashboard on my Stripe data” and get a working app with security, permissions, and compliance built in from day one. Whether on our cloud or self-hosted, create the internal software your team needs without compromising enterprise standards or control.

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. -

grafx - Extensible Java Graphics Package
Extensible Line-drawing & Polygon-filling Rasterization Libs for Java
Line-drawing and polygon-filling rasterization algorithms in Java. Simple 2D package and more complex 3D package with Z-buffering. Texture mapping not supported at the moment. Color interpolation for lines, Gouraud shading for polygons fully supported. Floating point vertex coordinates, not integer. Pixel-level aliasing, not endpoint aliasing. Doesn't use Bresenham line style! Works with all Java versions. No external dependencies. Suitable for study in academic institutions, especially as related to line-drawing accuracy. Particular attention to detail concerning chopping of accumulation errors, using a cast from 64 bit to 32 bit strategy, in the interval [1.0,2.0). Individual pixel errors with overlapping polygons or line segments are about one in a billion, but I can't reproduce any errors at the moment by using random number generation with tens of millions of cases. Emphasis not only on correctness, but also on performance for real-world use or hardware implementation. -

Automatic Drawing Generation
A canvas library for generating technical drawings
The ADG library (Automatic Drawing Generation) is a set of functions focused on automating the drawing of mechanical parts. It is not a CAD system but a GObject-based library where a custom application can put common CAD entities such as paths, hatches and dimensions, to automatically create technical drawings. A demo application is provided in order to show the capabilities of the canvas. Although it is possible to interact with the library directly in C (that is what the adg-demo program is doing), the canvas is expected to be used from higher level languages, much in the same way as what done in the GNOME stack. Lua bindings based on LGI are already provided out of the box. The adg-lua project, downloadable from the "Files" section, provides Lua programs and demos that leverages these bindings. -

Advanced Simulation Library
Free multiphysics simulation software package
Advanced Simulation Library (ASL) is a free and open source multiphysics simulation software package. Its computational engine is based, among others, on the Lattice Boltzmann Methods (http://en.wikipedia.org/wiki/Lattice_Boltzmann_methods) and is written in OpenCL (http://en.wikipedia.org/wiki/OpenCL) which enable extraordinarily efficient deployment (http://asl.org.il/benchmarks) on a variety of massively parallel architectures, ranging from inexpensive FPGAs, DSPs and GPUs up to heterogeneous clusters and supercomputers. The engine is hidden entirely behind C++ classes, so that no OpenCL knowledge is required from application programmers. ASL can be utilized to model various coupled physical and chemical phenomena and employed in a multitude of fields: computational fluid dynamics, virtual sensing, industrial process data validation and reconciliation, image-guided surgery, computer-aided engineering, high-performance scientific computing, etc.. -
