Hi ThreeJS Community! :waving_hand:

For the last two years we’ve been building something pretty wild, and we’re excited to finally share it: Ragnar, an app that lets anyone create 3D CAD models from a simple text prompt.

We visualize everything in real-time using Three.js, so you can go from:

thought → prompt → 3D model
…and then keep iterating until it’s ready for 3D printing or manufacturing.

What Ragnar does

  • Generate 3D CAD-style geometry from a prompt

  • Iterate fast: tweak the prompt and refine the model

  • Export for production: STL and STEP

  • Real-time interactive viewer powered by Three.js

Why we’re posting here
We’d love feedback from people who know 3D on the web best. If you have thoughts on:

  • viewer UX (controls, inspection tools, section cuts, measurement, etc.)

  • performance patterns / best practices in Three.js

  • CAD-ish visualization (edges, shading, material choices, grid, snapping)

  • exporting workflows or “gotchas” in production pipelines

…we’re all ears.

Try it / see it

If you’d like, just create an account and prompt whatever! We give all our users free credits when signing up, without having to setup any payment details at all!

Thanks for taking a look! :folded_hands:

what would also be awesome is the ability to upload a mesh model and it makes a step out of it.. yes i know it should be a fully closed model but even still this would be HUGE for the scan to Reverse engineer work flow..
