The part you need doesn't exist. Describe it.
Text to CAD for functional parts and assemblies.
Free designs are shared in the community gallery. Pro keeps them private.

Made with Ragnar
Real models from the community. Every shared model is a starting point: open one, remix it, and make it yours.

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

E03 · How It Works
From Idea to Reality in 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. Ragnar builds it in minutes.
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.

05 · Use Cases
What People Build
Functional parts, from print bed to plasma table. Designed in minutes, fabricated the same day.
FDM & Resin
Electronics enclosures, threaded caps and adapters, custom brackets and mounts, drone parts in PETG and TPU.
- Print-aware: wall thickness, bed size, orientation
- Watertight, manifold geometry on export
- Iterate until the fit is right
Engineering
Gearbox housings, tool turrets, linear slide beds, mold and nozzle assemblies, fixtures.
- Multi-part models with proper positioning
- Export STEP part by part into larger projects
- Minutes instead of hours on a blank canvas
Plasma & Laser
Plasma-cut brackets, gussets, mounting plates, tab-and-groove joinery, flange layouts.
- DXF export with CNC-ready layers (CUT, BEND)
- Speaks the trade: clevis, gusset, flange
- From sketch to cut file in one session
Hardware
Robot chassis, servo mounts, FPV drone brackets, PCB enclosures, sensor housings.
- Screw bosses and bolt patterns where you need them
- Material-aware: rigid PETG walls, flexible TPU mounts
- Multi-part assemblies with proper positioning
Product
Cabinets with joinery details, product concepts, architectural elements.
- Full 3D models plus DXF plans for panels
- Iterate materials and proportions in conversation
- GLB export for clients and collaborators
