Text to CAD: turn plain English into editable CAD models
TextoCAD is a free AI text to CAD generator. Describe a part the way you would explain it to a colleague, and get an editable parametric CAD model in your browser. Adjust dimensions with sliders and export STEP or STL, free to use. Paid plans only unlock a more powerful model and higher limits.
How text to CAD works
Traditional CAD software asks you to build geometry one operation at a time: sketch, extrude, fillet, pattern, and constrain. Text to CAD flips that around. You describe the result you want in plain English, and the AI engine produces the modeling steps for you as an editable parametric model.
A good text to CAD prompt names the part, the key dimensions, and the features. For example: "Create a mounting bracket 80 mm wide and 5 mm thick with four 6 mm holes and 3 mm corner fillets." The more specific your dimensions, the closer the first result is to what you need.
Why use text to CAD instead of drawing by hand
For simple mechanical parts, brackets, bushings, flanges, plates, and enclosures, describing the part is often faster than modeling it manually. You skip the blank-canvas problem and start from a working model you can refine. Because the output stays parametric, you keep full control over every dimension.
What you get
Every TextoCAD text to CAD generation is built to be edited, not just viewed.
Plain English prompts
Write what you want in normal language. No macros, no scripting, no command syntax to memorize.
Editable parametric models
Every generated model exposes dimensions as sliders so you can refine the design after generation.
Feature tree you control
See each modeling step as a feature you can toggle, inspect, and adjust.
Browser-native
Runs in the browser with no install. Preview models instantly on any modern device.
STEP and STL export
Export engineering-ready STEP files or STL meshes for 3D printing and manufacturing review.
AI design assistant
Refine the model by chatting. Ask for changes in plain English and iterate quickly.
Example text to CAD prompts
Use these as a starting point for your own designs:
- Create a metric involute spur gear with 23 teeth, module 2 mm, a 10 mm center bore, and 8 mm face width.
- Design a rectangular enclosure 120 by 80 by 40 mm with 2 mm walls and four mounting bosses.
- Model a flanged shaft coupling with a 20 mm bore, a 60 mm flange, and six bolt holes on a 45 mm circle.

Frequently asked questions
What is text to CAD?
Text to CAD is the process of turning a plain English description of a part into a 3D CAD model. Instead of drawing geometry by hand, you describe the dimensions and features you need and an AI engine generates an editable parametric model for you.
Is TextoCAD a free text to CAD generator?
Yes. TextoCAD is free to use. You can generate, edit, and export CAD models in your browser without paying. Paid plans are optional and only unlock a more powerful AI model and higher monthly limits for heavier use. Parameter slider edits, project saving, and basic STEP/STL export are always free.
Can I edit the model after generating it from text?
Yes. Every generated model is parametric. Dimensions appear as live sliders, and you can also ask the AI assistant for changes in plain English, so the design stays fully editable after the first generation.
What file formats can I export?
TextoCAD supports STEP export for engineering and CAD workflows and STL export for 3D printing. Basic exports are free at launch.
Do I need CAD experience to use text to CAD?
No. The point of text to CAD is to remove the learning curve of traditional CAD software. If you can describe the part you need, you can generate a starting model and refine it with sliders.
