Text to CAD: describe a part, get a STEP file

Describe any part in plain English and get an editable CAD model with STEP export in minutes.

Ragnar CAD turns your text descriptions into precise, editable 3D models. Describe a part with dimensions, features, and materials, and the AI builds true B-Rep geometry you can measure, modify, and manufacture from.

No credit card required. 15 credits a month.

New Design

STEP·STL·DXF·GLBReady to export

From description to editable STEP file

Specify exact measurements, add fillets and chamfers, request threaded holes or boolean cuts. The output imports directly into SolidWorks, Fusion 360, Onshape, or FreeCAD as a fully editable STEP file. You can also export STL for 3D printing, DXF for laser or plasma cutting, or GLB for web viewing.

Iterate on the CAD model in plain English

Refine your design by describing changes instead of navigating menus or learning hotkeys. Make it wider, add a 5mm fillet, move the mounting holes. Each request updates the existing model in place, so you never start over.

From a shelf hook to a full mechanism

Ask for a shelf hook, a ventilated electronics enclosure with a snap-fit lid, or a full mechanism like a spincast fishing reel with its crank and gear train. A simple part comes back in minutes, and a mechanism takes longer. Every part is real CAD geometry with proper faces, edges, and surfaces.

FAQ

Frequently asked questions

Text to CAD is the process of converting natural language descriptions into 3D CAD models using AI. You describe a part with dimensions, features, and materials, and Ragnar CAD generates a precise, editable 3D model you can export as STEP, STL, DXF, or GLB.

Ragnar uses AI to interpret your text description, then generates true B-Rep (boundary representation) geometry using a CAD engine. The result is a mathematically precise solid model that can be fully edited in SolidWorks, Fusion 360, or any professional CAD software.

Ragnar CAD exports STEP files for professional CAD editing, STL files for 3D printing, DXF files for laser and plasma cutting, and GLB files for web viewing. STEP is the industry-standard format compatible with SolidWorks, Fusion 360, Onshape, FreeCAD, and CATIA.

No. Ragnar CAD is designed for everyone from beginners to experienced engineers. Describe what you need in plain English and the AI handles the technical modeling. You can specify exact dimensions or keep it general.

A simple part like a bracket or a shelf hook comes back in minutes, and a mechanism like a spincast fishing reel takes longer. You can iterate by describing changes without starting over.

Yes. Ragnar generates B-Rep geometry with precise dimensions, threads, fillets, and boolean operations. The STEP files import into professional CAD software where you can add tolerances, run simulations, and prepare for CNC machining or injection molding.

Ragnar CAD produces true B-Rep geometry with STEP export, supports image input alongside text, and handles multi-part assemblies. Some other tools also produce B-Rep with STEP export, while others produce mesh-only output without STEP export.
