How to design a room in 3D in 4 steps
Move from a room template or 2D outline to a furnished, walk-through 3D space in four straightforward steps.
- Start
1. Set your room footprint
Pick a furnished or empty room preset, import a JSON/DXF file up to 15 MB, or draw walls, doors, and windows on the 2D canvas.
- Furnish
2. Place & size 3D furniture
Drag items from 8 room categories, then type exact width, depth, height, and elevation values to match real furniture specs.
- Style
3. Apply finishes & lighting
Compare 12 floor and surface materials, customize wall colors, and scrub the Day (06:00 to 18:00) or Night lighting controls.
- Explore
4. Walk through & export
Check sightlines in Walk mode or with Lower walls enabled, then save a 3D screenshot, GLB model, scaled PDF, or AI render.

Frequently Asked Questions
How does this work as home design software or a 3D room maker?
Unlike static rendering tools, this home design software and 3D room maker links a 2D drafting canvas directly to a live 3D scene. You draw or adjust walls, doors, and windows in 2D, then furnish, recolor, and walk through the exact same model in 3D.
Is this free online 3D room design software?
Yes. Manual 2D and 3D modeling, all 120 furnishing items, 12 material presets, Orbit/Top/Walk camera views, and all 7 file exports work online in your browser as free 3D room design software. Account credits apply only when you run optional AI layout proposals, AI renders, or walkthrough videos; see Pricing.

Can I upload a floor plan photo or render a 3D floor plan from an image?
The interactive planner imports .json project files and .dxf CAD drawings up to 15 MB, not raster photos or PDF scans. If you want to turn an existing 2D image into a rendered 3D floor plan overview, use the AI 3D Floor Plan Visualizer, or modify a plan image with the AI Floor Plan Editor.
Can I draw new walls in 3D or use the sun slider for exact solar studies?
New walls, doors, windows, and Demolish marks are drawn in 2D or Split view so dimensions stay accurate, while furniture placement and finish changes work directly in 3D. The Day (06:00 to 18:00) and Night lighting controls provide a visual preview of room ambiance rather than a site-specific solar study.
What is the difference between a 3D screenshot, GLB export, and AI Render?
A 3D screenshot saves your current viewport immediately as a PNG, and GLB exports the 3D geometry for external 3D apps, both included for free. The Render panel uses account credits to generate separate AI-styled presentation images or walkthrough videos from your scene.
