I wanted OpenSCAD with fillets and a C-like language. So I made one

hackerscad is a parametric CAD where the model is code. Type and the 3D view follows; round an edge with the mouse and the code is written for you. Exact solids, real threads, files for every printer.

What it does

hackerscad is a parametric CAD where the model is code. Type and the 3D view follows; round an edge with the mouse and the code is written for you. Exact solids, real threads, files for every printer. Paste this to it: it installs hackerscad's skill, then hackerscad itself if it's missing (asking you first) and the MCP server. Then it reads the language from docs written for agents, checks and renders its models, and shows them in your window. More below A small, sandboxed language with units, selectors and libraries. It diffs, versions and reviews like any other code. Fillets, holes, sketches on a face, parts moved and patterned: every click lands in the file, readable. 3MF with a colour…from hackerscad.com

    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…

    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…

    FluidCAD – Parametric CAD with JavaScriptApr 2026 · fluidcad.io · ▲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…
