Chili3d – A open-source, browser-based 3D CAD application

In plain words

Chili3D is an open-source, browser-based 3D CAD application that runs directly in web browsers without requiring installation. It uses OpenCascade compiled to WebAssembly and Three.js to deliver near-native performance for modeling, editing, and rendering. The application offers modeling tools for creating basic shapes and 2D sketches, advanced operations like boolean operations and extrusion, precise snapping and tracking, editing capabilities including chamfering and filleting, and measurement tools for angles and lengths. It is designed for anyone needing accessible CAD functionality online.

In the maker’s words, at launch

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…

  Open-sourcing our text-to-CAD app2025 · github.com · ▲179

  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…

  Cross-platform open-source 3D modeling software2018 · dust3d.org · ▲290

  Dust3D 1.0 is finally released — about 10 years after the first commit in December 2016. I posted a preview version here in April 2018 and a beta in December 2018. Back then I thought 1.0 was just around the corner, but I kept adding new features that I could barely find time to finish as a weekend side project. I finally got it done with GitHub Copilot, using models including Claude Opus 4.6, Raptor mini (Preview), Claude Haiku 4.5, and Claude Sonnet 4.6. It's a cross-platform low-poly 3D modeling app focused on making it fast to create game-ready characters and objects from scratch. Source…

  Vibe Code your 3D ModelsFeb 2026 · github.com · ▲61

  Hi HN, I’m the creator of SynapsCAD, an open-source desktop application I've been building that combines an OpenSCAD code editor, a real-time 3D viewport, and an AI assistant. You can write OpenSCAD code, compile it directly to a 3D mesh, and use an LLM (OpenAI, Claude, Gemini, ...) to modify the code through natural language. Demo video: https://www.youtube.com/watch?v=cN8a5UozS5Q A bit about the architecture: - It’s built entirely in Rust. - The UI and 3D viewport are powered by Bevy 0.15 and egui. - It uses a pure-Rust compilation pipeline (openscad-rs for parsing and csgrs…

  Talanoa▲340

  Hi HN, I’m a fullstack developer, and honestly, I’ve lost count of how many side projects I’ve worked on over the years. But one idea kept coming back to me: a different kind of email client. It first came to me in 2014: “What if we could handle emails more like conversations?” Every year, I’d revisit this concept in my “Build Notes.” Ten years later, no one had built exactly what I had in mind — so I finally decided to do it myself. That’s how Talanoa was born. I wanted something focused on people, not timelines. I was tired of marking messages as unread just to remember to reply later, or…

  I'm an airline pilot – I built interactive graphs/globes of my flights▲1,539

  Hey HN! Pilots everywhere are required to keep a logbook of all their flying hours, aircraft, airports, and so on. Since I track everything digitally (some people still just use paper logbooks!), I put together some data visualizations and a few 3D globes to show my flying history. This globe is probably my favourite so far: https://jameshard.ing/pilot/globes/all If you’ve got ideas for other graphs or ways to show this kind of data, I’d love to hear them!

  Workout.cool – Open-source fitness coaching platform▲827

  I was the main contributor to workout.lol, an open-source fitness app to easily build a workout routine. The project had traction (1.4k GitHub stars, 95 forks, ~20K visits/month), but was eventually sold due to video licensing hurdles. The new owner stopped maintaining it, and the repo went abandoned. Over the next 9 months, I sent 15 emails to try to save it : no replies. Feature requests & issues were ignored. The community was left with a "broken" tool let's say. I couldn't just let it die So I built the new version from scratch with the same open-source spirit, but a better…
