Describe the part. Get a clean 3D model.
Type a hook, a bracket, a gear or an enclosure with millimetre sizes. FreeTextToCAD builds it in your browser on a real CAD kernel and exports STL for your slicer or STEP for SolidWorks and Fusion.
Nothing to install. The CAD engine downloads once (about 60 MB), then every part builds on your device.
- Exact dimensions, any size
- STL, STEP and OBJ export
- Sliders to adjust after the build
- Name or photo keychain? Keychain Maker

Or start from a pre-filled prompt for a common part:
One part today, no CAD licence
Specific, dimensioned prompts give the best results. One or two sentences with millimetre sizes is ideal.
Describe
One part, with dimensions in millimetres.
Generate
The AI plans it and the kernel builds it in your browser.
Refine
Adjust with sliders or a typed change until it fits.
Export
Download STL, STEP or OBJ.
For printingSTL and OBJ
A clean, watertight mesh that slices without repair in Bambu Studio, PrusaSlicer or Cura.
- Exact millimetre dimensions
- Printed threads and gears with clearance
- Ready for any FDM or resin printer
For CADSTEP
Most AI generators hand you a mesh. FreeTextToCAD runs an OpenCascade B-rep kernel, so a cylinder is a cylinder, not a hundred flat facets.
- Opens as editable faces in SolidWorks, Fusion, Onshape
- Exact cylinders, planes and fillets
- Free CAD users: FreeCAD reads it too
Frequently asked
Is FreeTextToCAD free?
Yes. There is no account and nothing to install. Describe one part, generate the 3D model in your browser, and export STL, STEP or OBJ.
Can I export STEP?
Yes. The model is built on an OpenCascade B-rep kernel, so STEP export keeps exact cylinders, planes and fillets. Open it in SolidWorks, Fusion, Onshape or FreeCAD with no mesh faceting. STL and OBJ are there for slicers.
What kinds of parts work best?
Anything you can describe with sizes: hooks, brackets, washers, knobs, mounts, enclosures, trays, gears, threaded parts, adapters. Bigger things work too, such as a bench, a shed or a room at real size. Each generation builds one solid.
Do I need to install software?
No. Everything runs in your web browser. The CAD engine downloads once (about 60 MB) and then builds every model locally on your device.
Can it make screws, gears, and other hardware shapes?
Yes. Ask for bolts, nuts, knobs, gears, adapters and similar parts with the size you need. Printed threads and gears fit best with a little clearance, so test the fit on a short sample first.
Do you make assemblies?
Each generation builds one solid. For an assembly, generate the main part first and then each other part as its own prompt. CAD Studio offers early feature-based editing for sketching parts by hand.
Can I paste a full specification or brief?
Short works better. One or two sentences with millimetre sizes is ideal. Long documents with headers and bullet lists usually stop at the confirm step. The prompt contract guide shows how to split a brief into parts.
What about figurines, vases, logos and faces?
Figurines, characters, animals, vehicles and buildings from text are built as simple look-alike display models. A face, logo or photo becomes a keychain or tag in the Keychain Maker. To draw a freeform shape yourself, use CAD Studio.
