Frequently Asked Questions
Everything you need to know about designing 3D furniture with AI.
What is Prompt2CAD?
Prompt2CAD is a web application that uses AI to generate 3D furniture models from natural language descriptions. You chat with an AI designer, and it creates a parametric 3D model you can view, adjust, and export.
Who is Prompt2CAD for?
Anyone who needs custom furniture designs — interior designers exploring concepts, hobbyist woodworkers planning projects, homeowners visualizing built-ins, small furniture manufacturers prototyping, or architects creating bespoke pieces for spaces.
Do I need CAD experience to use Prompt2CAD?
No. You describe what you want in plain language. The AI handles geometry, dimensions, materials, and structural logic. You can refine the design conversationally — "add a drawer at the bottom" or "make the shelves thicker."
What kinds of furniture can it design?
Bookshelves, cabinets, pantries, desks, tables, room dividers, storage units, wine racks, wardrobes — essentially any furniture composed of panels, shelves, drawers, and structural elements.
What are parametric models?
Parametric models are driven by adjustable parameters — width, height, number of shelves, door style, etc. Change a parameter via a slider or number input, and the entire model recalculates and re-renders instantly. This lets you explore design variations without starting over.
Can I upload reference images?
Yes. You can paste or upload images into the chat. The AI uses them as design inspiration — it will analyze the style, proportions, and features and incorporate them into the model.
What export formats are supported?
Six formats: STEP (.step) for CNC manufacturing, DXF (.dxf) for CAD software, OBJ (.obj) for 3D meshes, STL (.stl) for 3D printing, GLB (.glb) for web visualization, and PNG (.png) for viewport screenshots.
How much does Prompt2CAD cost?
New users get free trial credits ($2.00 worth of AI usage). After that, credits are available in pay-as-you-go top-ups starting at $5 via Stripe. Costs depend on conversation length — a typical furniture design session uses a small fraction of the minimum top-up.
Where are my designs stored?
Designs are stored in your browser's local storage. You can create multiple projects, switch between them, and they persist across sessions. Export your designs to files for permanent backup.
Can the AI see the 3D model it's building?
Yes. The AI takes screenshots of the viewport to verify its work — typically from multiple angles. If something looks wrong, it reads the code, identifies the issue, and fixes it iteratively.
What AI model powers Prompt2CAD?
Anthropic's Claude Sonnet, accessed through the Anthropic API. The AI has been instructed with furniture design expertise, realistic material dimensions, and best practices for parametric modeling.
Do I need to install anything?
No. Prompt2CAD runs entirely in your web browser. There's nothing to download or install — just visit prompt2cad.com and start designing.
