Text to CAD with AI Editable OpenSCAD, free

Describe a part in words and the AI writes an OpenSCAD program for it: code-based CAD where every dimension is a named parameter. The model opens with sliders for those parameters, so you can resize it without another prompt and download the .scad source.

Free. Use your own Anthropic or OpenAI key.

Also from Innerscene: Circadian Lab, a free lighting calculator for room illuminance, melanopic EML, and glare.

Need flat parts for a laser, Cricut or CNC router? The same AI also makes cut files as SVG and DXF, checked for the kerf.

How it works

  1. 1. Describe it or add a photoType what you want in plain words, with sizes if you know them, or add a photo as a reference. Describe an object or a person.
  2. 2. The AI builds and checks itThe AI writes an OpenSCAD program for an object, or sets up the character generator for a person. It looks at six rendered views of the result and fixes what is wrong, up to five builds per message.
  3. 3. Refine and exportThe model opens in the viewer at real size. Ask for changes in the chat, move the sliders, then download it or pick a format from the Export menu.

Why make it with AI here

  • The output is readable CAD code you own, which you can version, share and edit in OpenSCAD.
  • Sliders for each parameter turn one prompt into a family of sizes.
  • The AI checks six rendered views of each build and corrects mistakes before you see the result.

Prompts to try

Click one to open it in the AI panel, then change the sizes to suit.

Getting the CAD model out

  1. Download the .scad file from the version list to keep the editable source.
  2. Export STEP from the Export menu for other CAD programs.
  3. Export STL or 3MF to 3D print it.

The .scad file is the parametric model. STEP and other exports are faceted snapshots of the current slider values.

Best export formats: OpenSCAD (.scad), STEP, STL

Good to know

OpenSCAD is built from solids and booleans, so it is not suited to freeform surfaces. STEP export is faceted and carries no feature history.

Cost and privacy

You use your own Anthropic or OpenAI API key. It is stored only in your browser and sent only to that provider, which bills you directly: a model typically costs $0.05 to $0.30 at Standard quality and up to about $1 at Detailed, and Innerscene charges nothing. Your key and prompts are not sent to Innerscene; we record anonymous usage statistics such as the steps used, the model chosen, token counts, a cost estimate and whether a model was made.

Questions

▶What is text to CAD?
Describing a part in words and getting a CAD model back. Here the AI writes OpenSCAD code that builds the part with named dimensions.
▶Can I edit the code?
Yes. Download the .scad file and open it in OpenSCAD, or ask the AI to change it in the chat.
▶Does the .scad file open in OpenSCAD?
Yes. It is a plain OpenSCAD program, so you can open, edit and render it in the desktop OpenSCAD app.
▶Can I export to STEP?
Yes. STEP is in the Export menu and comes out as a faceted solid.
