Plan Chat

The AI floor plan generator that draws real CAD

Most AI floor plan generators give you a picture. Plan Chat gives you a CAD drawing: an AI drafter lays out the plan on a structural grid, with wall thicknesses, door swings, windows, furniture, dimension chains, room numbers and areas, a room schedule and a legend, on standard layers. You watch it being drawn, change it by chat or with CAD tools, and download DXF, DWG and PDF.

Some new accounts get their first drawing free while we test it.

CAD floor plan drawn by the AI drafter: structural grid, hatched walls, doors with swings, dimension chains, room tags with areas, room schedule and legend
A family house, 12 × 10 m, drawn from a short brief in about three minutes. Watch it being drawn.

How it works

  1. 1. Describe or upload

    Type the building (rooms, sizes, storeys, plot) or attach a sketch or an image of a plan you want redrawn.

  2. 2. Generated live as CAD

    The drafter sets the grid and draws walls, openings, fixtures, dimensions and room tags step by step, then checks its own drawing.

  3. 3. Iterate, then export

    "Make the living room 1 m deeper", "move the garage to the left": each change is a new version you can go back to. Export DXF, DWG or PDF any time.

Generator plus editor

After the AI is done, the same file is open in a browser CAD editor with snaps, layers and the usual modify commands.

Measured, not guessed

Areas and dimensions are computed from the drawn geometry, so the room schedule always matches the plan.

3D and renders from the same drawing

The 3D model is built from the CAD walls and openings, and you can render any version photorealistically.

What you get

DXFLayered, opens in AutoCAD, BricsCAD, DraftSight, LibreCAD, QCAD, Rhino, SketchUp (import) and Revit (link).
DWGAutoCAD 2010 format, so every AutoCAD from 2010 on and most DWG-compatible programs open it.
PDFA3 landscape sheet plotted to a true scale (1:50, 1:100 …) with a border and a title block.

Plus a 3D model built from the same walls and openings, photoreal renders of any version, and every version kept with its own link.

Layers in the drawing

A-WALLwalls, with A-WALL-PATT for the cut hatch
A-DOOR / A-GLAZdoors with swings, windows
A-GRIDstructural grid with bubbles (A, B, C … / 1, 2, 3 …)
A-ANNO-DIMSdimension chains, overall and per bay
A-ANNO-TEXTroom names, numbers and areas, room schedule
A-FURN / A-FLOR-FIXTfurniture, kitchen and bathroom fixtures
A-FLOR-STRS / A-SITE / A-PLNTstairs, site elements, trees

Tips for the best result

  • Give the overall size or the area you aim for; the drafter fits the rooms to it.
  • Name must-haves ("en-suite", "pantry next to the kitchen", "stairs in the centre").
  • Say metres or feet; the whole drawing, dimensions and areas follow.
  • Start broad, then refine with short change requests.

Questions

Is there an AI that generates CAD floor plans?

Yes. Plan Chat generates a floor plan as a real CAD drawing (layered DXF and DWG) from a description or a sketch, with walls, doors, windows, dimensions, room areas and a room schedule, and lets you keep editing it with CAD tools.

What is the best AI generator for AutoCAD floor plans?

For a plan you want to continue in AutoCAD, pick a tool that exports layered DWG or DXF with real entities rather than an image. Plan Chat does that, draws live so you can follow every step, and includes a browser CAD editor.

Can the AI change the plan after it is drawn?

Yes. Describe the change in a sentence and the drafter edits the drawing; untouched parts stay where they are. Every change is a version with its own link, and undo or restore is free.

Which buildings can it draw?

Houses, apartments, ADUs, cabins and other single floors of residential and small commercial buildings. Draw multi-storey buildings floor by floor.

Are the plans ready for a permit?

No. They are AI concept drawings and can contain mistakes. Have a licensed architect or engineer check and complete the plan before building or applying for a permit.

Try it with your own plan

Drawings, changes and renders use credits from an AI Architectures plan, from $12 a month; DXF, DWG and PDF downloads are included. See pricing.
