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…

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.

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…

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…

I'd like to share a new workbench I've been working on called DiffCAD. Coming from a software engineering background, not having the ability to properly diff my CAD model changes was driving me crazy. This project scratches my own itch, and maybe someone elses', too! I'm open to feedback, ideas, and contributions. Cheers!

LuaCAD models solids in Lua rather than the OpenSCAD language, with operator overloading for CSG (`a + b`, `a - b`, `a * b`). It ships with a CLI and a desktop app, including a preview area and a text editor. I've always been a big fan of OpenSCAD, but the SCAD language itself is unfortunately quite cobbled-together and is a very poorly designed programming language. LuaCAD takes all the good parts of OpenSCAD and combines them with one of the best scripting languages. It has now completely replaced OpenSCAD for me, and I think it provides a better experience than OpenSCAD for all use cases.…
