Getting started with Sketch2Space

Updated 2026-06-26convert floor plan sketch to 3D onlinesketch to 3D modelhow to make a 3D model from a floor plan

This guide takes you from a floor plan sketch to an editable 3D model in a few minutes. You don't need any CAD experience — upload a picture of your plan and Sketch2Space does the drawing for you.

What you'll need#

A floor plan sketch as an image (JPG or PNG) or a PDF. Hand-drawn, a marketing brochure, or a clean CAD drawing all work.
A free Sketch2Space account.

Clearer input gives a better model. A straight-on photo or scan with readable walls beats a blurry, angled photo. See tips for the best results.

Convert your first sketch#

Create an account and open the app. Sign up free, then open your dashboard.
Create a project and upload your sketch. Drag in your image or PDF, or click to browse.
Let the AI read your plan. Sketch2Space works in two stages — first it finds the structure (rooms, walls, doors, windows, stairs), then it builds a realistic 3D preview.
Review and adjust. Walk around the 3D model and adjust anything that looks off.
Export your model. Download a .dae (CAD) file ready for SketchUp, Blender, and other tools. See Export to CAD.

How the two stages work#

Sketch2Space builds your model in two passes so you can catch problems early:

Structure — the AI extracts the floor plan: rooms, walls, doors, windows, and stairs. This is the single source of truth for your model's shape.
Realistic — the same model with realistic materials and lighting for a clean preview, plus CAD export.

Edits you make in either view are saved back to the structure, so both views always match.

FAQ#

Do I need CAD experience to use Sketch2Space?#

No. You upload a picture of your floor plan and the AI does the drawing. You only review the result and export it.

What file types can I upload?#

Images (JPG, PNG) and PDFs, including multi-page architectural PDFs. Hand-drawn, brochure, and CAD-style plans all work.

Is the 3D model editable?#

Yes. You can review and adjust the model before you export.

Can I use Sketch2Space on my phone?#

Yes — fully. The whole flow works in a mobile browser: upload, edit, and export. See Use it on your phone or tablet.
