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.

Complete Guide — 12 Steps

From floor plan
to 3D render

Every step from uploading your first floor plan to exporting a photorealistic render — with real screenshots from inside the app.

Step 01

Upload Your Floor Plan

Click the upload button and drop in any 2D floor plan — a photo, scanned PDF, CAD export, or even a hand sketch. Strukt AI accepts JPG, PNG, PDF, and DWG. No clean linework needed; the AI corrects blurry or imperfect scans automatically.

JPG, PNG, PDF and DWG all work

Blurry photos and hand sketches are fine

Max file size is 50MB

Higher resolution = more accurate wall detection

Step 02

Crop to Your Floor Plan

After uploading, a crop tool lets you trim the image to just the floor plan area. Remove any surrounding white space, title blocks, or legends so the AI focuses only on the geometry. You can skip this step if your image is already well-framed.

Crop tightly around the walls — exclude scale bars and text

Click Skip if your image is already clean

Landscape orientation generally works best

Step 03

Run Inference

Hit the Process button to start the AI inference. The spatial engine reads the floor plan, detects every wall, door, window, and room boundary, then converts them into an editable SVG. Processing typically finishes in under 60 seconds.

A worker status indicator shows if the engine is online

Your job is queued automatically if a worker is busy

The result is a fully editable 2D vector — not a static image

Step 04

Calibrate Real-World Dimensions

Select the Ruler tool (C), click on any wall you know the real length of, and type the measurement. This sets the scale so all dimensions in the 3D model are accurate — room volumes, door sizes, ceiling heights, and export measurements will all match reality.

Use a wall whose length you know — an exterior wall works well

Enter the length in meters (e.g. 4.5)

Calibration only needs to be done once per project

Without calibration you cannot render or export

CSelect Ruler / Calibrate tool

Step 05

Edit Walls, Doors & Windows

Every element in the 2D editor is live. Click any wall, door, or window to select it — a context toolbar appears at the top with actions specific to what you picked. Drag to reposition, use the handles to resize, and cycle through door/window types with a single button.

Select a wall to Join it to another, toggle Railing, or add a Label

Cycle window types: Standard → Sliding → Large → High → Bathroom

Swap any door to a window or vice versa without losing position

Duplicate any object with Ctrl+D

RRotate selected object

DelDelete selected

JJoin two walls

LLabel wall or object

Ctrl+DDuplicate

Step 06

Switch to 3D View

Click the 3D button in the topbar to instantly extrude your 2D floor plan into a full 3D model. Walls, doors, windows, and railings all appear at their correct heights. Orbit around the model to inspect the structure from any angle before adding materials or rendering.

The model auto-generates — no manual work needed

Railing walls appear as glass post-and-rail in 3D

Sliding windows show as floor-to-ceiling glass panels

Switch back to 2D at any time to make edits

Step 07

Use Wireframe Mode

Toggle the wireframe button to see the raw 3D geometry without materials. This is useful for checking wall thicknesses, verifying that all walls are correctly connected, and spotting any gaps or doubled geometry before you invest time in texturing and rendering.

Wireframe helps debug floating or disconnected walls

Use it to check door and window placement in 3D

Toggle off to return to the shaded material view

Step 08

Enable FPV — Walk the Space

Switch to First Person View (FPV) to walk through the space at eye level. This is the most powerful way to check ceiling heights, door widths, sight lines, and room proportions before anything is built. Navigate with WASD or arrow keys and look around with the mouse.

Use FPV to spot rooms that feel too small or corridors that are too narrow

Check sight lines between rooms — does the layout feel open or cramped?

Switch back to Orbit mode to get an overview at any time

W A S DWalk forward / left / back / right

↑ ↓ ← →Alternative movement

MouseLook around

Step 09

Capture & Render

Open the FPV Render panel, position your camera to the angle you want, and click Capture. Write a short prompt describing the style (e.g. 'modern minimalist living room, warm lighting, oak floors'). Optionally add 1–3 style reference images. Hit Generate to produce a photorealistic render.

FPV Standard (FLUX) costs 50 credits — great for quick previews

Adding style references guides the material and lighting aesthetic

Pro render (Gemini, 110 credits) gives higher fidelity

Multiple renders can be queued — they run in parallel

Step 10

View & Toggle Render in 3D

Once a render completes, you can overlay it on the 3D scene to see how the AI interpretation maps to the geometry. Toggle the render on and off to compare the photorealistic output against the raw 3D model. This helps you decide if you need to adjust camera angle or prompt.

The render overlay is toggled in the FPV Render panel

Use it to check if furniture placement matches the render output

If the angle looks off, reposition and re-capture before rendering again

Step 11

Compare Before & After

The compare slider in the render gallery lets you drag between the raw FPV screenshot (before) and the AI-rendered output (after). This is the clearest way to show clients the transformation — from a plain 3D model to a fully styled, photorealistic room.

Drag the slider left and right to reveal before vs after

Use this in client presentations to show the AI's impact

Step 12

Export in Any Format

Click the 3D Export button in the topbar to download the model in your preferred format. GLB works for web and most 3D tools, Blender (.blend) gives you the full scene graph, SketchUp (.dae / Collada) for design work, and Revit (.ifc) for BIM workflows. SVG exports the 2D vector for further editing.

GLB — universal, works in web viewers, Unity, Unreal

Blend — opens directly in Blender with materials

DAE/SKP — SketchUp Pro compatible

IFC — Revit, ArchiCAD, and BIM platforms

SVG — take the 2D vector into Illustrator or AutoCAD

FurnAI — Photo to 3D
