Agentic AI CAD

Design a custom bookshelf by describing it

Floor-to-ceiling libraries, cube storage, ladder shelves — real dimensions and shelf spacing you adjust with sliders or a sentence. Export STEP, DXF, or STL.

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.

3D bookshelf model with oak wood shelves generated by AI in Prompt2CAD

Generated with Prompt2CAD — brief the agent, refine the model, export the CAD.

Whether you need a floor-to-ceiling library wall, a compact floating shelf unit, or an asymmetric modern bookcase, Prompt2CAD generates accurate 3D bookshelf models from a simple text description. The AI understands shelf spacing, material thickness, structural support, and standard furniture dimensions. Every model is parametric — change the width, height, number of shelves, or shelf depth with a slider and the entire design updates instantly. Export to STEP for your CAD workflow, DXF for AutoCAD, STL for 3D printing, or OBJ/GLB for visualization.

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.

How the CAD agent helps

Any bookshelf style

Open shelves, closed cabinets, ladder shelves, cube storage, asymmetric designs, built-in bookcases — describe the style and the AI builds it.

Parametric dimensions

Adjust width, height, depth, shelf count, and shelf thickness with sliders. See the bookshelf update in real time as you explore variations.

Realistic proportions

The AI knows standard bookshelf dimensions, material thicknesses, and structural requirements. Models come with accurate proportions from the start.

CAD-compatible exports

Export to STEP or DXF with millimeter-accurate dimensions. Import into Fusion 360, FreeCAD, or AutoCAD for further refinement or share with your cabinet maker.

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."

DIY builder, Italy
