Text to CAD: 3D Model of a Part

Write what part you need and its dimensions, and the model builds an engineering 3D model. You can rotate it on the page and download STEP for CAD, STL for 3D printing or a CadQuery script for changing dimensions.

Part type, dimensions in millimeters, holes and slots. One part at a time gives a more accurate result.0 / 2000

Try an example:

A model costs $0.25 and usually takes under a minute, sometimes up to 10 minutes, and longer in a queue. If it fails, you are not charged. The finished model is saved in Files.

Examples of what works today

Real results with no manual edits; the descriptions are translated from the original requests. Click an example to rotate the model and download the files.

How it works

The model reads your description and writes a parametric CadQuery script, and the script builds the part. If it fails to build, the model corrects it and tries again. It usually takes under a minute, sometimes up to 10 minutes. The finished model is saved in your Files.

What works well and what does not

Standard parts with clear geometry come out best: spur gears, flanges, brackets, plates and shafts. Assemblies of many parts are still mediocre, since parts may not fit and small features get simplified. It does not make models from photos, figurines or characters, or standards-compliant technical drawings.

How to write a description

Name the part type, give dimensions in millimeters, and describe the holes: how many, for which fasteners and where. List features like a hub, keyway, gusset, ribs or chamfers. For a gear, give the module, tooth count and face width. Build one part at a time, and check dimensions in your CAD program before manufacturing.

Frequently asked questions

How much does it cost?

$0.25 per finished model, charged from your balance. You need an account, and if the build fails you are not charged.

Can it make a 3D model from a photo?

No. It builds only from a text description of the part type and dimensions, and makes engineering parts rather than figurines or characters.

Which formats can I download?

STEP, STL, GLB, OBJ and the Python CadQuery script used to build the model, plus an image with four views and an archive of all files.

Will it open in SolidWorks or Fusion?

Yes, use the STEP file. It opens in SolidWorks, FreeCAD and Fusion as a solid body.

Is the model suitable for 3D printing?

Yes, download the STL. Dimensions are in millimeters and it opens in any slicer. Check wall thickness and small holes before printing.
