Turn a Hand-Drawn Floor Plan Into a 3D Model — AI (2026)
Sketched a floor plan on paper? Take a photo and Strukt AI repairs the wonky lines, reads the rooms and builds an editable 3D model you can walk through, render and export. No CAD, no clean drawing, no download — free to try.
Not every floor plan starts in CAD. A lot of them start as a sketch on paper — a homeowner planning a renovation, a designer roughing out a layout, a builder scribbling on-site. You can turn that sketch into an editable 3D model without ever drawing it “properly.”
Convert a 2D floor plan to 3D — free, in your browser
Upload a PDF, image, or CAD file and get an editable, photorealistic 3D space in under a minute. No download, no 3D skills, no credit card.

Photograph your sketch
Take a normal phone photo of the hand-drawn plan and upload it at app.struktai.work. It doesn't need to be neat, straight, or to scale.
AI cleans it up
Strukt straightens the wonky lines, detects rooms and wall thicknesses, and reconstructs an editable 3D model from the messy drawing.
Set the real scale
Calibrate the whole model from a single known measurement — one wall length — and every room snaps to correct real-world dimensions.
Edit, render, export
Adjust walls, doors, windows, ceiling height and materials; generate a photorealistic render or a first-person walkthrough; export to GLB, BLEND, DAE or IFC.

Frequently asked questions
Can AI turn a hand-drawn floor plan into a 3D model?
Yes. Take a photo of your sketch and upload it to app.struktai.work. Strukt AI straightens the hand-drawn lines, detects rooms and wall thicknesses, and builds an editable 3D model — you don't need a clean or scaled drawing.
Does my sketch need to be to scale?
No. Upload the photo as-is, then calibrate the whole model from a single known measurement (say one wall length), and everything scales to correct real-world dimensions.
Can I edit the model and export it after?
Yes. The result is fully editable — adjust walls, doors, windows, ceiling height and materials — and you can render it, walk through it in first-person, or export to GLB, BLEND, DAE or IFC.
Is it free to turn a sketch into 3D?
Yes. There's a free tier, it runs in the browser, and there's nothing to install.

Editable 3D Model From a Floor Plan — Edit Walls, Doors & Export GLB (2026)
Most AI tools turn a floor plan into a pretty 3D render you can't change. Strukt AI reconstructs it into a real, editable 3D model — click a wall to change its thickness, length or height, move doors and windows, then export to GLB, BLEND, DAE or IFC. Plus photorealistic renders, AI mood boards, and material texturing. Here's the difference between an AI render and an editable model, and how to get one free.
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.
