Blender is the gold standard for architectural visualization — physically correct lighting, ray-traced shadows, cinematic depth of field. The problem is that getting a floor plan into Blender as a proper 3D model has always required a human modeler or days of manual work. Strukt AI eliminates that step entirely.
Upload an image of any 2D floor plan — a scan, a photo, a PDF saved as PNG — and Strukt reconstructs it into a fully editable 3D model in your browser. From there you can render it photorealistically without leaving the tab, or export a native .blend file and keep working in Blender with all geometry, materials and room labels already in place.
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.
Convert your planWhat “photorealistic” actually means here
Most floor plan tools produce a real-time 3D preview — flat lighting, no shadows, plastic-looking surfaces. Strukt's HD render engine is different: it's a path tracer running in WebGL, the same technique used by Blender Cycles. Light bounces between surfaces, casts soft shadows, and reflects off materials based on real physical properties. The result looks like a studio render, not a game engine screenshot.
- —Physically correct light bounces — light fills rooms realistically, not with flat ambient
- —Soft shadows and penumbra — shadows have natural edges, not harsh CG outlines
- —PBR material reflections — wood grain, polished concrete, fabric all respond to light differently
- —Runs in your browser — no render farm, no queue, no cloud GPU fees
From floor plan to Blender render in four steps
Upload your floor plan
Drop a PNG, JPG or WEBP image of your plan at app.struktai.work (save PDF or CAD drawings as images first). The AI repairs broken lines, infers wall thickness, and detects every room, door and window automatically — even from a hand-drawn sketch or a photo of a printed plan.
Edit the 3D model
The plan becomes real, editable geometry: click a wall to adjust its thickness or ceiling height, move doors and windows, calibrate scale from one known measurement so the whole model is dimensionally correct. No 3D skills required.
Render in HD — in your browser
Switch to HD mode and Strukt path-traces the space. Capture individual rooms as PNGs, or use Room Tour to render every room automatically and download the full pack as a ZIP — ready for client presentations, listings, or handover packs.
Export to Blender for the final mile
When you need Blender-level control — custom lighting rigs, compositing, animation — export the native .blend file. It opens in Blender with the full mesh, materials and room geometry already set up. Start where Strukt left off, not from scratch.
Why this beats manually modeling in Blender
The traditional workflow is: get floor plan → model walls in Blender → add doors → add furniture → set up lighting → render. A single apartment takes an experienced Blender artist 6–12 hours. With Strukt, the model is generated from the plan. You skip straight to the creative part.
Room Tour: every room rendered automatically
Capturing a render of every room in a multi-bedroom apartment used to mean manually positioning the camera in each space, adjusting framing, and rendering one by one. Room Tour does it automatically — Strukt moves through the model, sets an optimal camera angle in each room, and delivers a complete render pack you can drop straight into a client deck or property listing.
Who uses Strukt for Blender visualization
- —Architects presenting early-stage designs to clients without commissioning a 3D studio
- —Interior designers showing clients what a furnished space will look like before purchase orders go in
- —Property developers producing off-plan renders for every unit from a single floor plan type
- —Blender artists who want to skip the modeling step and get straight to lighting, compositing and animation
Frequently asked questions
Can I get a photorealistic render from a floor plan without using Blender?
Yes. Strukt AI path-traces your floor plan directly in the browser — no Blender install needed. You upload a 2D plan, the AI builds the 3D model, and the HD render engine produces physically correct lighting and shadows in one click.
Does Strukt export a native Blender file?
Yes. Every Strukt project can export a .blend file — a native Blender file with the full editable geometry, materials and textures. Open it in Blender and continue exactly where Strukt left off.
What makes Strukt's renders photorealistic?
Strukt uses a path-tracing render engine (the same technique professional studios use) running via WebGL in your browser. It simulates real light bounces, soft shadows, and material reflections — not a flat real-time preview.
Is it free to render a floor plan photorealistically?
Yes. Strukt has a free tier that includes the HD path-traced render engine. Upload your floor plan, generate the 3D model, switch to HD mode and capture renders — no credit card required to start.
Can I render every room at once, not just one screenshot?
Yes. Strukt's Room Tour feature automatically moves through every room and captures a render of each one. Download the full set as a ZIP — useful for property listings, client decks, and handover packs.
