Floor plan to 3D model in minutes — the zdraw workflow
Turn a 2D floor plan into a fully-furnished 3D model in under 10 minutes. Walls, doors, windows, furniture, lighting and AI rendering — all in your browser.
The shortest path from sketch to 3D
The reason most floor plan apps stop at 2D is that 3D usually means a second piece of software, a model import dance, and lighting setup. zdraw collapses that into a single tool — your 2D plan IS the 3D model.
Here's the workflow most users settle into after a few projects.
1. Block out rooms first, not walls
Drawing walls one at a time leads to corner mismatches and gaps. Draw rooms as rectangles or polygons first (any closed shape qualifies), then click Build. zdraw produces consistent walls with proper mitred corners. Reshape a room → re-Build → everything stays clean.
2. Keep wall thicknesses honest
The Build pipeline uses 150 mm for exterior walls and 100 mm for interior partitions by default — sensible defaults for residential. Override per-wall if needed; cladding and base walls layer on top.
3. Doors and windows are anchored to rooms
Every door and window remembers which room edge it sits on, not just which wall. Reshape the room, rebuild the walls, the openings reattach themselves to the right new wall.
4. Lighting drives the render quality
A flat-lit 3D preview looks fine, but a real interior depends on lights. zdraw ships spot lights, area lights and a path-traced sun. Drop a few before you render — the difference between a flat preview and a hero shot is mostly lighting.
5. AI for style, path-tracing for accuracy
Two render modes:
daylighting, glass, metal, real shadows.
stylised image. Useful for moodboards or client previews where speed and atmosphere matter more than literal accuracy.
- Path Trace — physically-correct ray tracing. Great for accurate
- Enhance (AI) — turns the current view (or a path trace) into a
You can chain them: render with path tracing, then pass the result through AI Enhance with "Last generated AI image" as the source to build up successive looks.
6. Save your renders
Hit "Add to Render Gallery" on any preview to save it under your account. Renders survive page reloads and you can reload any past render into the preview window to edit further.
That's the full loop. Open the tutorial for a hands-on walkthrough or the gallery for example scenes you can remix.
