Vibe Code your 3D Models
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…

In plain words
SynapsCAD is an open-source desktop application for designing 3D models using OpenSCAD code. It combines a code editor, real-time 3D viewport, and an AI assistant that lets users modify designs through natural language prompts with supported LLMs like OpenAI, Claude, and Gemini. Built entirely in Rust using Bevy and egui, the application compiles code directly to 3D meshes without requiring external tools. The software is designed for 3D modeling enthusiasts and engineers who want to blend traditional code-based CAD workflows with AI-assisted design capabilities.

The AI-powered 3D CAD IDE — edit code, visualize in 3D, and reshape your designs with natural language. - timschmidt/synaps-cad
OpenSCAD editing, exact CSG, interactive visualization, and AI-assisted modeling in one Rust application. SynapsCAD is an early prototype. OpenSCAD compatibility is incomplete; concise bug reports with a reproducing source file are welcome. SynapsCAD parses and evaluates OpenSCAD source without invoking the OpenSCAD executable. It presents the result in a Bevy viewport, exports STL, OBJ, or 3MF, and can ask local or hosted language models to revise the current design. The compiler is also available as a Rust library. Install a stable Rust toolchain, clone this repository beside the Hyper dependencies named in Cargo.toml , and run: cargo run --locked The editor is on the left and the…from github.com

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

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.).

- IBI built a wizard to turn ideas into AI coding agent-ready specsNov 2025 · vibescaffold.dev · ▲71
I created vibescaffold.dev. It is a wizard-style AI tool that will guide you from idea → vision → tech spec → implementation plan. It will generate all the documents necessary for AI coding agents to understand & iteratively execute on your vision. How it works: - Step 1: Define your product vision and MVP - Step 2: AI helps create technical architecture and data models - Step 3: Generate a staged development plan - Step 4: Create an AGENTS.md for automated workflows I've used AI coding tools for awhile. Before this workflow (and now, this tool), I kept getting "close but not quite" results…
DSLCad – a programming language and interpreter for building 3D models2023 · github.com · ▲198Hey 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.
GPT image editing, but for 3D models2025 · adamcad.com · ▲188Hey HN! I’m Zach one of the co-founders of Adam (https://www.adamcad.com). We're building AI-powered tools for CAD and 3D modeling [1]. We’ve recently been exploring a new way to bring GPT-style image editing directly into 3D model generation and are excited to showcase this in our web-app today. We’re calling it creative mode and are intrigued by the fun use cases this could create by making 3D generation more conversational! For example you can put a prompt in such as “an elephant” then follow it up by “have it ride a skateboard” and it preserves the context, identity and…

Hello my name is Ben Ward for the past 3 years I have been remastering the financial game Wall Street Raider created by Michael Jenkins originally on DOS in 1986. It has been a rough journey but I finally see the light at the end of the tunnel. I just recently redid the website and thought maybe the full story of how this project came to be would interest you all. Thank you for reading.
