Floor plan to 3D render — from the plan you already have

Your layout is the fixed part. Room positions, wall lines, door and window openings and the overall proportions all carry through to the render. What the AI supplies is everything the drawing leaves out — materials, furniture, light, colour and depth — which is why the output reads as a visualisation of your plan rather than a generic apartment that happens to look nice.

You choose the viewpoint in words. An aerial dollhouse view of the whole floor is the usual request and the one that sells a layout fastest, while an eye-level view into a single room shows what being in it would feel like. Say which you want in the prompt, alongside the style and the materials.

Furniture is placed to suit the room sizes rather than dropped in at random, so a narrow bedroom gets a sensible bed wall and a wide living room gets a proper seating arrangement. To restyle one of those rooms in detail once the layout is agreed, take the rendered view into interior AI.

What it will not do is redraw your plan. It will not move a wall, resolve a circulation problem or invent a layout from a brief — it renders the plan you give it. If you need drawings back out of a render rather than an image out of a plan, that is the opposite direction and Detail AI handles it.

A hand sketch on graph paper, a CAD export, a screenshot of a PDF page, an estate agent plan saved off a listing, a photograph of a plan pinned to a wall — all of them are valid, because the tool reads an image rather than a file format. There is no DWG or RVT parser, so export a PNG or PDF from CAD instead of uploading the native file and expecting it to open.

Clean line work wins. Dimensions, tags, north points, hatching and title blocks are line work too as far as the model is concerned, and heavy annotation ends up rendered into the image as texture across the floor. Export a stripped-back, geometry-only version and the render improves immediately.

Plans with room labels usually do better than plans without them, because the words tell the AI what each space is for and the furniture follows. A drawing marked kitchen, bath and bedroom gets furnished far more sensibly than an unlabelled set of boxes.

If the drawing you have is a perspective sketch rather than a plan, sketch to render is the right tool for it, and a site-scale layout with roads, blocks and landscape belongs in masterplan rendering instead.

Three things carry a plan render: the style, the finishes and the camera. "Scandinavian interior, pale oak floors, white walls, soft daylight, aerial dollhouse view" hands the model all three. "Make it look nice" hands it none, and the result shows it.

Name the flooring explicitly. It is the largest continuous surface in any plan view and it sets the temperature of the whole image more than any other single choice — the same reason material swap exists as its own tool for finished renders.

For wordings you can copy rather than invent, there is a tested interior design prompt library and a lighting and mood set. Generate two or three directions from the same plan and put them side by side, rather than trying to get the first one perfect.

A modelled plan in SketchUp, Revit or ArchiCAD gives you dimensional accuracy, a coordinated model and drawings that come out the other end. A plan render gives you an image in about thirty seconds. They answer different questions, and it is worth being clear about which question you actually have in front of you.

For the early conversation — does the client understand the layout, do they like the direction, which of these two options do they prefer — the image wins on speed by an enormous margin. For anything that gets built, priced or submitted, the model is still the model, and no amount of rendering changes that.

The two combine well in practice. Render the plan to agree a direction, then model the one that survived; or model first and use the free SketchUp plugin to render the viewport whenever an image is needed. If what you want is a downloadable mesh rather than a picture, image to 3D converts a plan image into a GLB file.

A plan render costs 30 credits. Every account renews 100 free credits to start with no card, so the free tier covers three plan renders — enough to test the tool on your own drawing, not enough to produce a scheme set. Paid plans start at $29/month for 1,000 credits, with one-time packs from $15 if your work is project-shaped rather than continuous; the pricing page has the full breakdown.

Free output is watermarked and carries no commercial licence. Any purchase removes both, which matters the moment the image is going into a listing, a brochure or a client report rather than staying on your own screen.

And the honest ceiling: this is a presentation tool. Rendered plans are fast and persuasive, but they are not measured drawings, the furniture is indicative rather than specified, and nothing that comes out of here should be priced or built from. Agree the direction with it, then do the work properly.
