From an image to an editable floor plan

An image contains pixels rather than editable spaces. Import a clear PNG drawing, let Build3D Floorplans analyse the layout, then check and adjust the detected geometry in the editor.

Prepare your drawing

Use a straight, top-down PNG with a plain background and clear boundaries. Crop unnecessary margins and remove unrelated artwork. Keep a known measurement visible. If your source is JPEG, export a PNG first; changing only the file extension does not convert it.

A practical example

Start with the sample 20 m by 12 m layout below. The centre aisle separates four spaces. After importing the PNG, compare the detected areas with the drawing, calibrate the full width to 20 m and check the 12 m depth. Then rename the spaces and review their openings.

Example input: a 20 by 12 metre layout with four spaces around a central aisle — Illustrative input, not a guaranteed conversion result. Use the known 20 m width to check scale; inspect every detected space before saving.

Review before publishing

Zoom into small gaps and labels. Check that a thick stroke has not become an extra object and that neighbouring spaces remain distinct. An image's pixel dimensions are not its physical dimensions: confirm metres against a known length.

What to expect

Only PNG image input is currently supported. Blurred photographs, perspective distortion, coloured backgrounds and tiny text reduce detection quality. Conversion is a starting point for editing, not a guarantee of survey-grade accuracy or a photorealistic render.

Common questions

Does one PNG use one credit?

One successfully converted PNG uses one import credit. Manual corrections and private previews do not use credits. Selecting the same file for a deliberately new conversion does use another credit.

Automatic drawing analysis, with you in control

Build3D Floorplans uses drawing analysis and OCR, not a trained generative AI model. It reconstructs supported geometry for you to review. It does not certify measurements or replace a construction survey.

Your floorplan stays private until you explicitly publish it. A public 3D viewer sends geometry to the visitor's browser; no web viewer can prevent screenshots or guarantee copy protection.
