What this site covers ​

This is the documentation for prompt2cad.com: designing in the app and integrating the CAD agent through the Developer API.

Building an integration? Start with the Developer API quickstart for API keys, image inputs, generation and refinement, export downloads, and working JavaScript and Python examples. API usage shares your account credit balance.

The fastest path through is:

1. Sign up — Google sign-in and trial credits.
2. Your first design — prompt → plan → model in three steps.
3. Interface tour — what every panel does.

Once you are comfortable with the basics, Working with Designs covers prompt craft, iteration, materials, and project management. Exporting walks through every output format. Billing explains how credits work.

What Prompt2CAD is good for ​

Designed for:

• Custom furniture and built-ins — cabinets, desks, wardrobes, tables, bookshelves, beds, vanities, and fitted kitchen or storage layouts.
• Mechanical parts — brackets, fixtures, housings, jigs, mounting plates, enclosures — anything you want to describe and iterate before sending to CAD.
• DIY and woodworking — shelving, planters, shop fixtures, simple builds where you want a parametric model rather than a one-shot sketch.
• Parametric variation — building one model that you can stretch to any width, swap finishes on, change counts on, without re-drawing.
• Handing off to downstream tools — STEP into Fusion / SolidWorks / FreeCAD, 3D DXF into compatible CAD software, DAE into SketchUp Free, STL or 3MF into a slicer.
• Visualisation — GLB for AR / web previews, OBJ + MTL for Blender, PNG screenshots for slide decks.

Not designed for:

• Production-ready fabrication drawings. Geometry is faithful to the millimetre on export, but the agent is a design tool, not a CAM tool. A fabricator should still review STEP output before cutting.
• Sub-millimetre tolerances or GD&T. For precision mechanical work, treat exports as a starting point and tighten dimensions and tolerances in your downstream CAD.
• Animated assemblies. Doors, drawers, and other moving parts have open/close parameters that move geometry, but Prompt2CAD does not export rigged animations.
