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 helps you turn ideas into editable, dimensioned 3D models. Explore variations, review the geometry, and refine the design through conversation — real parametric CAD, not just a polygon-soup mesh.
No CAD experience needed · STEP, DXF, STL, 3MF, OBJ, and GLB exports

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.
Share or keep designing
Share a view of your design, review a preliminary parts list, or export STEP, DXF, OBJ, STL, or GLB to continue reviewing and refining it in other tools.

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
Explore custom furniture, built-ins, workshop projects, fixtures, mechanical parts, and products with an agent that helps develop the whole model. Adjust dimensions, compare ideas, and keep refining real parametric CAD — 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.
Keep Your Design Moving
STEP and DXF for further CAD work, OBJ and GLB for visualization, PNG for presentations, and STL or 3MF for preparation and validation in a 3D-printing slicer.
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.
Preliminary Parts Summary
Open a geometry-derived preliminary 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 review and estimating.
Model review and refinement
The agent can inspect screenshots and geometry code to identify issues and revise the model. These checks help the design process; they do not certify accuracy, fit, or safety.
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.
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."

DeepSeek V4.1 Flash 1017 token rates: $1.20 input / $0.024 cached input / $4.80 output per million tokens. Output includes reasoning. Cache pricing applies only to provider-reported cache hits. Each successful non-zero-token call rounds up to whole credits, with a one-credit minimum.
Illustrative DeepSeek 1017 usage, not measured averages: a new model uses 10 calls of 100k input and 3k output tokens each; an update uses 2 calls of 100k input and 4k output each. Ranges compare 90% input cache hits with no cache hits; the first new-model call is uncached. Output includes reasoning. Actual usage can fall outside these ranges; renders and other AI tools cost extra. Pack counts are either-or examples, not combined allowances or guaranteed completed designs.
