Image to CAD
Image to CAD: Turn Any Image into a 3D Model
Upload a napkin sketch, photo, or technical drawing. Get a precise, editable CAD model with STEP export.
Stop redrawing from scratch. Ragnar CAD converts any visual reference into precise 3D CAD models: hand-drawn sketches, product photos, engineering diagrams, whiteboard drawings. The AI interprets shapes, dimensions, and features from your image and builds editable B-Rep geometry you can refine and export.
No credit card required. 15 free credits monthly.
From photo to fitted part
Photograph a circuit board and ask for a protective case around it. Snap the parts you already have and get the chassis that ties them together. Drop in a technical drawing and let the AI extract the geometry automatically.
Combine images with words
Add a text description alongside your image to specify dimensions, materials, or features the photo alone can't capture. The AI handles perspective correction, scale estimation, and feature extraction, so a reference photo becomes a finished STEP file without tracing geometry by hand.
Refine the CAD model in conversation
Once the initial model is ready, iterate by describing changes. Ask for tighter tolerances, additional mounting holes, or a different wall thickness and Ragnar updates the model in place. Export STEP, STL, DXF, or GLB when it's right.
Real Examples
See It in Action
Real prompts, real results. Watch how Ragnar CAD generates precise, editable models.
01
Make a protective case for this circuit board
Reads the board from a photo and builds a ventilated case with port cutouts and a snap-fit lid around it.
02
A wall rack that docks these six shaker bottles
Interprets the bottles from a photo and generates a wall-mounted holder with six sized openings.
03
A chassis that fits these wheels and this battery pack
Builds an RC car chassis with axle mounts and a battery tray sized to the parts in your photo.
