AI-powered parametric CAD

Describe what you want to build.
Get real, editable CAD.

From custom furniture and built-ins to mechanical parts and product designs, Prompt2CAD plans, models, checks, and refines the geometry with you. Adjust dimensions, generate a cut list, and export for downstream CAD, fabrication workflows, or 3D printing, not just a polygon-soup mesh.

No CAD experience needed · STEP, DXF, STL, 3MF, OBJ, and GLB exports

Up to 160 trial credits where available · No credit card required

Brief → plan → model

Describe the object, dimensions, materials, and constraints. The agent turns the brief into editable CAD.

Select → ask → refine

Select the part you mean, ask for a change, and let the agent inspect the updated model.

From a brief or existing model to editable CAD

No CAD experience needed. The agent handles the modeling loop while you control the object, dimensions, and final export.

Brief the agent or open a model

Describe the object, upload a reference image, or open an existing DWG, DXF, SKP, OBJ, STL, or GLB model and continue designing from it.

The agent plans and builds

The agent asks for missing details when needed, plans the structure, and uses CAD tools to create real parametric geometry at the dimensions you specified.

Inspect and refine

The agent renders and checks its work from multiple angles. Use controls or say "make it wider" or "add a back panel" to refine the same model.

Present or hand off

Review the geometry-derived parts list, download it as CSV, or export STEP, DXF, OBJ, STL, or GLB for downstream CAD, prototyping, and production preparation.

In the press

“Here, you get a parametric 3D model you can actually work with in a CAD tool.”

Plan the build

Know every part before you build

Turn the model into a preliminary parts list for estimating and workshop planning. Repeated parts group automatically, hardware stays separate, and every row carries dimensions, quantity, material, and finish.

From idea to a real CAD model

Build custom furniture, built-ins, workshop projects, fixtures, mechanical parts, and products with an agent that can reason across the whole model. Get real parametric CAD, a geometry-derived cut list, and exports — not a polygon-soup mesh.

A CAD agent, not a prompt box

Describe what you need in plain language. The agent can clarify the brief, plan the structure, build geometry, and refine it through conversation.

Export to Every Format

STEP and DXF for CAD tools, OBJ and STL for 3D printing, GLB for web viewers, PNG for presentations. Every dimension in real-world millimeters — no unit conversion needed.

Parametric Controls

Every model comes with adjustable parameters — width, height, shelf count, door style. Use sliders and toggles for instant design exploration without starting over.

Cut List & Parts Summary

Open a geometry-derived parts list directly from the model. Matching parts are grouped with stable IDs, L × W × T dimensions, quantities, and materials, then downloadable as CSV for estimating and workshop planning.

Plans, inspects, and corrects

The agent takes screenshots of its work from multiple angles, reads the geometry code, diagnoses visible issues, and corrects the model before handing it back.

Photoreal materials

Walnut grain that runs the right way. Brushed brass that catches light along the grain. Honed marble with real veining. Bouclé that reads as fabric, not paint. The model picks from a curated PBR library of woods, stones, metals, fabrics, leather, and glass — high-resolution CC0 textures from Polyhaven and ambientCG, applied at real-world scale.

Reference Image Upload

Paste or upload photos or sketches of what you want to build. The AI analyzes style, proportions, and features to incorporate them into your design — no manual tracing needed.

Import CAD & 3D Models

Open DWG, DXF, SKP, OBJ, STL, or GLB files as Prompt2CAD projects. Modify parts, add parametric features, combine source and generated geometry, and export the completed design.

Geometry-grounded renders

Turn your exact CAD model into a faithful, client-ready render. The geometry anchors the image, so proportions and details stay tied to the design you approved.

Start with something you want to build

Explore furniture, built-ins, workshop projects, fixtures, and functional parts, or brief the CAD agent on your own custom object.

Built for makers and engineers

From DIY builders and product designers to mechanical engineers, people are using Prompt2CAD to design and iterate on real projects.

"I spent weeks trying other AI and modeling tools for built-in storage in oddly shaped rooms. Prompt2CAD was the first that gave me a precise design I could verify and build from, without needing a CAD background."

DIY home renovator, United States

"I designed a custom L-shaped walk-in closet, 240 by 140 cm, with oak panels, hanging sections, drawers, and recessed lighting. I described the layout in detail and refined the proportions as I went. Saved me a long session in modeling software."

Furniture designer, East Asia

"I needed a custom planter for a terrace with an unusual stepped floor, so the base had to follow an L-shape. I described the geometry, refined a few details, and walked away with something I could actually build from. Much faster than starting from scratch in CAD."
