What it does

Free online CAD editor for 2D drawing — open DXF files, draw geometry, add dimensions, and export PDF. No installation, no account required.

Open DXF files, draw geometry, add dimensions, and export PDF — without installing a single thing. A free alternative to desktop CAD that runs in any modern browser. A complete CAD command set, accessible via toolbar, keyboard shortcut, or the command terminal. Lines, arcs, circles, polylines, splines, ellipses, text, and multileaders. Everything you need for 2D geometry. Move, copy, rotate, mirror, scale, offset, trim, extend, fillet, chamfer. Full modify suite via toolbar or command terminal. Linear, aligned, radius, diameter, angular, and continue dimensions. All stored as standard DXF DIMENSION objects. Freeze, lock, isolate, and configure color, linetype, and lineweight per layer.

    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…

    Hello HN! I found that picking out plausible but diverse skin tones for my digital art and game development projects was kind of difficult, and I got curious about if there was a way to define a color space that made it easy. I've built a color picker and procedural generation algorithm based on the space as well as a bunch of other fun js features and demos throughout the page that use the equations. If you find it interesting, I have lots of explanations of how I built it and what properties the space has. The methodology might be a bit shaky, but hopefully the result is as helpful for…

  • I trained a 125M-parameter transformer to autocomplete piano performances in real time (~108 notes/sec on an iPhone 15). The idea is basically GitHub Copilot or Tabnine, except instead of prompting it with code, you prompt it by playing a few notes on a MIDI piano. The model then continues what you played, entirely on-device. The app is free if anyone wants to try it. Happy to answer questions about the model, training, Core ML, or the many things that didn't work.
