The part you need doesn't exist. Describe it.
Text to CAD for functional parts and assemblies. Then simulate it, render it, animate it and find the components to buy.
Free designs are shared in the community gallery. Pro keeps them private.
Or start by remixing
01 · From the Community
Made with Ragnar
Real models from the community. Every shared model is a starting point: open one, remix it, and make it yours.
55,000+ parts built by 25,000+ makers
02 · Features
Starts with CAD. Doesn't stop there.
Most AI CAD tools stop at the model. Ragnar keeps going, the way an engineer would: once the model exists, it answers the questions that come next, so you can improve the design before you build it.
CAD
01 / 04
01
Text or image to CAD
Describe it (“a wall mount for my router, with slots for the cables”) or drop in a sketch, a photo or a drawing. Ragnar builds a precise B-Rep solid, not a mesh.
02
Iterate with words
“Make it taller.” “Add a 5 mm fillet.” “Cut a slot here.” Extrude, fillet, loft and boolean cuts, driven by conversation. Point at exact geometry with @bracket.face when you need surgical control.
03
Inspect and export
Rotate, zoom, check every detail. Then STL for your printer, STEP for manufacturing or any other tool, DXF with clean layers for the plasma table, GLB for the web.
04
Built for teams
Private projects, a shared workspace, versions and checkpoints, invited editors, and admin visibility of who used what.

05
Simulate
Will it hold?
Run a FEM simulation on the model you just made. Find the thin wall or the weak boss before you build it, not after.
Simulate
06
Render
How will it look?
Renders in the materials and lighting you ask for, for a client, a product listing or a pitch deck. No export, no second tool.
07
Animate
How does it move?
Exploded views and motion animations that show how the parts fit together and how the mechanism works.
08
Source the components
What do I buy?
Ragnar searches the web for the screws, bearings, motors and boards your design calls for, and gives you a parts list with links.
Source
What do I need to buy for this?
Here is what the enclosure calls for:
- 4×M3 × 10 socket head screw
- 4×M3 heat-set insert
- 1×40 mm 5 V fan
- 1×USB-C power socket
- 1×ESP32-S3 board
- 1×SHT40 sensor board
09
Wire it
How does it connect?
Circuit diagrams for the electronics inside the enclosure you just designed, with the components you sourced.
Wire
All of it in one conversation.
03 · How It Works
From Idea to Reality in 4 Steps
Design against the real part, not just the render
Describe or show your idea
Type what you need, upload a photo or drawing, or start from a shared model. Ragnar builds it in minutes.
Iterate until it's right
“Make the pins thinner.” “Add a cable slot on the back.” Refine by describing changes. Need surgical control? Point at exact geometry with references like @bracket.face.
Check it before you build it
Simulate the load. Render it for the client. Pull the parts list. Find out now, not after the build.

Export and build
STL straight to your 3D printer. DXF with clean layers for your plasma or laser table. STEP for manufacturing or other tools, whole model or part by part. Your model stays live in Ragnar.

STEP for CAD software, STL for 3D printing, DXF with clean layers for CNC, laser, and plasma cutting, and GLB for web and presentations. Every plan exports all four.
Credits are used while Ragnar works on your design. Exports don't use credits.
No. If you can describe your part, Ragnar can build it. Experienced engineers get precision; beginners get results without the learning curve.
Ragnar builds real CAD models to the dimensions you specify. Every part can be measured, verified, and fabricated directly.
Yes. Everything you create is yours to fabricate, sell, and manufacture, including your remixes.
Business puts a company on a single shared credit pool: one subscription and one invoice for up to 25 users, a shared workspace alongside private projects, and per member usage visibility for admins.
