Strukt AI is an AI-native spatial design platform that converts 2D architectural floor plans into fully editable 3D spaces in seconds. It combines spatial intelligence, AI furniture placement, and real PBR material rendering so architects, interior designers, and real estate professionals can deliver photorealistic visuals without manual 3D modeling.

How does Strukt AI convert a 2D floor plan to 3D?

Upload any PDF, CAD, or image floor plan. Strukt AI's spatial engine digitizes dimensions and wall boundaries, automatically extrudes them into an accurate 3D structural model, detects and decomposes furniture into editable components, then lets you apply real PBR materials and render photorealistic visuals — all in under a minute.

What file formats does Strukt AI support for floor plans?

Strukt AI accepts PDF, CAD (DWG/DXF), and common image formats (PNG, JPG) as floor plan input. The AI repairs broken lines and inconsistent dimensions automatically.

Is Strukt AI free to use?

Yes, you can start building on Strukt AI for free at app.struktai.work. No credit card is required to try the core 2D-to-3D conversion and furniture placement features.

Who is Strukt AI designed for?

Strukt AI is built for architects who need rapid design visualization, interior designers who want AI-assisted space planning, real estate developers who need buyer-ready renders at scale, and prop-tech platforms that want to embed spatial AI into their product.

How is Strukt AI different from traditional 3D design software?

Traditional 3D tools like Revit or SketchUp require manual modeling that takes hours or days. Standard Gen-AI image tools are fast but produce non-editable outputs. Strukt AI combines speed with production-grade editability — you get an accurate, fully manipulable 3D model from a floor plan in seconds, with real brand materials and natural language editing commands.

Can I edit furniture and materials after the 3D model is generated?

Yes. Strukt AI's Furn AI system decomposes furniture into individual components so you can hot-swap pieces, match them to real brand catalogs, change flooring, apply paint colors, and re-render instantly. Nothing is static baked geometry.

How long does it take to generate a 3D space from a floor plan?

Strukt AI generates the initial 3D structural model in seconds. Full furniture placement and material application typically completes in under a minute, depending on the complexity of the floor plan.

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

Have your floor plan as a PDF? Upload it and Strukt AI reads the walls, doors and rooms straight from the PDF and builds an editable 3D model in your browser — then render it photorealistically or export to GLB, BLEND or IFC. Free, online, nothing to install.

Akash · Strukt AI·August 29, 2026·5 min read

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. Upload the PDF and Strukt AI reads it directly.

How PDF → 3D works

Upload the PDF

Drop your floor plan PDF at app.struktai.work. Vector PDFs read cleanest, but scanned or image-based PDFs 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. Upload the PDF at app.struktai.work and Strukt AI reads the walls, doors, windows and rooms directly from it, then reconstructs an editable 3D model in your browser — no need to redraw or export to CAD first.

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

Both work. Vector PDFs give the cleanest read, but the AI also handles scanned or image-based PDFs — it repairs broken lines and infers wall thickness, so even a photographed or exported PDF converts.

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.
