Design built-in storage for the room you actually have
Sloped ceilings, alcoves, uneven walls, and changing ideas — describe your room and get an adjustable, dimensioned CAD model without learning CAD first.
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.
Prompt2CAD helps DIY homeowners plan one-off storage for rooms that standard plans and configurators cannot fit. Start with the real space — wall lengths, ceiling slopes, alcoves, windows, skirting, and other obstacles — then design wardrobes, shelves, drawers, and cabinets inside it. Revise the same model through conversation as your ideas change instead of redrawing everything or repeatedly briefing a freelancer. The result is real parametric CAD geometry, not a polygon-soup mesh. Inspect it in 3D, review a geometry-derived preliminary cut list with part dimensions and quantities, and export STEP or DXF for further checking in SketchUp, FreeCAD, or with a carpenter. Verify site measurements, joinery, hardware clearances, and production details before making cuts.
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.
Start with a guided brief, not a blank canvas
Choose Guided setup in a fresh project and Prompt2CAD will help turn your room, storage needs, and unusual constraints into a structured CAD brief before it models anything.
Choose the closest category
Select Rooms & built-ins, then choose Storage wall or Other built-in as the closest starting point.
Answer the guided questions
Fill in room dimensions, openings, obstacles, storage zones, materials, and clearances. Recommended values help when you are unsure.
Add what makes yours different
Use the description and text fields for sloped ceilings, chimney breasts, uneven walls, special drawers, or any other must-have detail.
Review and generate
Check the assembled design brief, click Generate model, then keep refining the resulting CAD through conversation.
How the CAD agent helps
Start with the room, not a generic cabinet
Map wall lengths, changing ceiling heights, alcoves, windows, doors, skirting, and other fixed constraints before adding storage. The design begins with the space it must fit.
No CAD experience required
Describe the room and the build as you would to a woodworker. The agent handles the CAD operations while you review the dimensions and shape in 3D.
Change your mind without starting over
Ask for wider drawers, fewer shelves, a different door layout, or another material. The agent revises the same parametric model so you can compare ideas before committing.
Review before the first cut
Inspect dimensions and a geometry-derived preliminary cut list, download it as CSV, or export STEP and DXF for downstream review. Confirm site, joinery, hardware, and fabrication details before building.
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."

Brief the CAD agent
Include dimensions, constraints, materials, and intended use when you know them.
Parts list and CAD exports
Review a geometry-derived list of part IDs, dimensions, quantities, and materials, download it as CSV, or export the model for downstream CAD and prototyping. Verify production details before fabrication.
