    I'm currently developing Chili3D, an open-source, browser-based 3D CAD application. By compiling OpenCascade to WebAssembly and integrating Three.js, Chili3D delivers near-native performance for powerful online modeling, editing, and rendering—all without local installation. Access it here: https://github.com/xiangechen/chili3d Features: Modeling Tools: Create basic shapes (boxes, cylinders, cones, etc.), 2D sketches (lines, arcs, circles, etc.), and perform advanced operations (boolean operations, extrusion, revolution, etc.). Snapping and Tracking: Precisely snap to…

    Hey HN! I'm Zach from Adam (https://adam.new/). We’re building an AI co-pilot for mechanical CAD software. As part of our broader research, we built a browser-based Text-to-CAD app (https://news.ycombinator.com/item?id=44182206) and are now open sourcing it. This is a React SPA with a Supabase backend. What it does: * Generates parametric 3D models from natural language descriptions, with support for both text prompts and image references * Outputs OpenSCAD code with automatically extracted parameters that surface as interactive sliders for instant dimension…

    Hello HN users, This is a CAD by code project I have been working on on my free time for more than year now. I built it with 3 goals in mind: - It should be familiar to CAD designers who have used other programs. Same workflow, same terminology. - Reduce the mental effort required to create models as much as possible. This is achieved by: - Provide live rendering and visual guidance as you type. - Allow the user to reference existing edges/faces on the scene instead of having to calculate everything. - Provide interactive mouse helpers for features that are hard to write by code: Only 3…

    Hey HN. Over the last half a year I have been working on a 3D CAD programming language called DSLCAD. Today I am here to show my first release! It is heavily inspired by OpenSCAD which got me hooked on the idea of a CAD programming language and what it can do. Please let me know what you think. Ill be in the thread to answer any questions you may have.

    Cadseer is in the same genre as: solidworks, inventor, freecad etc... Cadseer is alpha software, so lots of missing features, bugs, crashes, file incompatibilities etc... About me: I spent 15 years designing stamping dies on a high end cad system. During that time, I also developed and marketed extensions/plugins toward that cad system. Through that experience, I came disillusioned with 'vendor lock-in' and proprietary software in general. I basically retired, took the vow of poverty and moved all my computing to open source. I have since, and continue to, try and improve the open…

    Hello, guys~ I recently developed a data exploration and visualization app which can be used as a different type of open-source alternative to Tableau. It is extremely easy to embed in your apps just as a react component. The original purpose is to develop a lite plugin that can be easily embedded in most cases, it doesn't have to be a large BI, but a lite graphic plugin. GitHub: Kanaries/graphic-walker, https://github.com/Kanaries/graphic-walker The main features implemented: * A user-friendly drag-and-drop-based interaction for exploratory data analysis with…

    Hi everyone started this project a year ago to generate the CAD for a Jet Engine Axial Compressor. I am now open sourcing this tool that can take in a JSON file with specs and generate the CAD assembly. Still has a lot of work to improve designs but there isn't anything the Open Source community can't accomplish!
