The part you needdoesn't exist. Describe it.

Text to CAD for functional parts and assemblies: enclosures, mounts, adapters, brackets, multi-part mechanisms. Describe it, iterate in conversation, export for your printer, CNC table, or CAD software.

Text to CAD, Simplified

Turn text descriptions into professional CAD models. From beginners to experts, everyone works faster with AI-powered CAD generation.

01

Text to CAD Generation

Just describe what you need. 'A phone stand' or 'M8 threaded hole, 20mm deep'. Ragnar turns your text into precise CAD models instantly.

Text → CADThe Ragnar app with a router wall mount generated from the prompt: a wall mount for my router, with slots for the cables
02

Turn Any Image into CAD

Upload any sketch, photo, or technical drawing. From napkin sketches to engineering diagrams, Ragnar turns them into precise, editable CAD models you can actually use.

03

Iterate with Words, Not Tools

Need changes? Just say it. 'Make it taller', 'Add a 5mm fillet', 'Create a cutout here'. No hunting through menus.

IterateA prompt referencing the case lid face turns a plain case into one with four screws
04

Professional Operations

Extrude, fillet, loft, boolean cuts. The full power of professional CAD, driven by conversation.

Industry-Standard Export

Export as STL for 3D printing or STEP for further editing. Works with any CAD software.

03 · How It Works

From Idea to Realityin 3 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. Be as simple or as detailed as you want.

New Design

Iterate Until It's Perfect

'Make the pins thinner.' 'Raise the whole post system.' 'Add a cable slot on the back.' Refine by describing changes, no menus, no feature trees. Need surgical control? Point at exact geometry with references like @bracket.face.

Export and Build

STL straight to your 3D printer. DXF with clean layers for your plasma or laser table. STEP for your CAD software, whole model or part by part. Print it, test the fit, then come back and refine. Your model stays live in Ragnar.
