Strukt AI turns a 2D floor plan image into a furnished 3D home in your browser. It reads the walls, doors, windows and room names from your drawing, designs and furnishes every room, and lets you walk through it with baked, realistic lighting, render photoreal images and export the model. It is built for interior designers, builders and homeowners.

Which files can I upload?

PNG, JPG or WEBP images of your floor plan, up to 15 MB on the homepage upload. Scans and phone photos work. If your plan is a PDF or a CAD (DWG/DXF) file, export or screenshot it as an image first — direct PDF and CAD upload is not supported yet.

How long does it take?

About 5 minutes from uploading your plan to an editable 3D model, for a typical floor plan. Larger or less clear plans can take longer. Rendering, furnishing and material changes happen after that, at your own pace.

How accurate is the 3D model?

Accuracy depends on how clear your drawing is. Clean, high-resolution plans give the best results. Some walls, openings or room boundaries can be read wrongly, and dimensions are estimates, so check the model and correct anything the AI got wrong. Strukt AI is for visualisation and design, not for construction drawings or permit submissions.

You can start free: every account gets 10 floor plans a month with the Free model, plus the 2D editor, 3D view, texturing and export, with no credit card. For the Pro model (rooms and names, automatic furnishing), baked walkthroughs and AI renders you buy credits: 2,000 credits cost ₹200, with no subscription, and they never expire while your account is active.

Can I edit the model after it is generated?

Yes. It is a real 3D model, not a picture. You can adjust walls, doors and windows, move, turn, resize or delete furniture (the AI re-plans the rest of the room around your changes), change floors, paint and other finishes, and re-render whenever you like.

Does it work for houses with more than one floor?

Yes. Add up to three upper floors to a house; Strukt lines them up and stacks them in 3D. Furnishing and baking the whole house, and walking up the stairs between floors, are rolling out now.

Can I export to other software?

Yes. Export to GLB and DAE (Blender, Unity, Unreal, Three.js), native BLEND, and IFC for Revit, ArchiCAD and other BIM tools, so you can continue in your own workflow.

Can I use the renders to market a property?

Yes, as visualisations. Renders are AI-generated and are labelled as such. Do not present them as photographs of a finished property, and remember that furniture, materials and lighting are approximate.

Who owns my designs, and is my data private?

You keep ownership of your original designs. Private projects are not shown publicly unless you publish them to the community. We do not sell your data, and you can ask us to delete your account and files at any time. See our Privacy Policy for details.

Convert a PDF Floor Plan to 3D — Free AI, No Download (2026)

Architects, agents and builders almost always have their floor plans as a PDF — exported from CAD, downloaded from a listing, or scanned from paper. The good news: you don't need to redraw it or open CAD to get a 3D model. Save the PDF page as an image, upload it, and Strukt AI reads the plan from it. (Direct PDF upload isn't supported yet — the image step takes a few seconds.)

Convert a floor plan to 3D, free, in your browser

Upload an image of your plan (PNG, JPG or WEBP) and get an editable, furnished 3D model in about 5 minutes. No download, no card.

How PDF → 3D works

Turn the PDF page into an image

Open the PDF and export the floor plan page as a PNG or JPG (most PDF viewers have "Export as image"), or take a high-resolution screenshot. Crop away title blocks and borders.

Upload the image

Drop the image at app.struktai.work. Clean vector PDFs exported at high resolution read best, but scans work too — the AI repairs broken lines and infers wall thickness.

AI reconstructs the geometry

Walls, doors, windows and rooms are detected automatically and rebuilt as a real, editable 3D model — not a flat picture.

Edit, render, or export

Click a wall to change thickness or height, move doors and windows, then generate a photorealistic render, walk it in first-person, or export to GLB, BLEND, DAE or IFC.

Because the plan is turned into editable geometry, a PDF you couldn't change becomes a model you can refine, render and hand off to Blender or Revit.

Why not just an image generator?

Image-generator tools can make a pretty 3D-looking picture from a PDF, but you can't edit the result — move a wall and it's gone. Strukt reconstructs the actual model, which is what you need if the plan will change or feed a real 3D/CAD pipeline.

Frequently asked questions

Can I convert a PDF floor plan to a 3D model?

Yes. Save the PDF page as a PNG or JPG (or take a screenshot), upload the image at app.struktai.work, and Strukt AI reads the walls, doors, windows and rooms, then reconstructs an editable 3D model in your browser — no need to redraw it. Direct PDF upload is not supported yet.

Does the PDF need to be vector or can it be a scan?

Both work once saved as an image. A vector PDF exported at high resolution gives the cleanest read, but scans work too — the AI repairs broken lines and infers wall thickness.

Is the converted 3D model editable?

Yes. It's a real model, not a flat render. Click a wall to change thickness, length or ceiling height, move doors and windows, then render it photorealistically or export to GLB, BLEND, DAE or IFC.

Is converting a PDF floor plan to 3D free?

Yes, there's a free tier and it runs entirely online in your browser — nothing to download or install.
