   Chili3d – A open-source, browser-based 3D CAD application▲408

   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…

   Cadseer. a parametric solid modeling CAD desktop application▲102

   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…

   Graphite, a Blender-inspired 2D procedural design Rust app▲785

   For the past three years I've been building what I hope will be the next Blender, tackling the lack of any good 2D design or image editing tools outside the Adobe monopoly. This was our first year participating in Google Summer of Code and this Q3 update includes the big payoff from that, covering the most progress we've made so far as a project. If you're a Rust dev, consider getting involved as we apply for the next GSoC in the new year— you could be our intern next summer :) Q3 progress report: https://graphite.rs/blog/graphite-progress-report-q3-2024/

   FluidCAD – Parametric CAD with JavaScript▲160

   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…

   Forge – Guardrails take an 8B model from 53% to 99% on agentic tasks▲687

   Hi HN, I'm Antoine Zambelli, AI Director at Texas Instruments. I built Forge, an open-source reliability layer for self-hosted LLM tool-calling. What it does: - Adds domain-and-tool-agnostic guardrails (retry nudges, step enforcement, error recovery, VRAM-aware context management) to local models running on consumer hardware - Takes an 8B model from ~53% to ~99% on multi-step agentic workflows without changing the model - just the system around it - Ships with an eval harness and interactive dashboard so you can reproduce every number I wanted to run a handful of always-on agentic systems…

   Open-sourcing our text-to-CAD app▲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…

   SuperCraft▲283

   Hi there, SuperCraft is generative AI tool for industrial designers. It offers a collaborative node based canvas where users can sketch, and convert the sketches to high quality 2D and 3D renders of their products. It looks like if Figma and ComfyUI had a baby. With SuperCraft, designers can generate sketch ideas from textual descriptions of the product, or directly draw on the canvas, or upload images of their sketches. They can further enrich the sketches and turn them into highly realistic renders of the products using textual descriptions. The renders generated are both 2D and 3D, and…

    Cross-platform open-source 3D modeling software▲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 Models▲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…
