✨ What's New

Two-pass extraction agent + first-run guideNEW
2026-07-06
🪄 Analyze is now an agent loop: grid-grounded reading with drafting-symbol expertise (door arcs, window bands, wall poché), deterministic wall regularization (axis-snap · junction-weld · collinear-merge), then the agent overlays its own walls on your drawing and corrects them. Plus a ⬡ welcome guide on first launch (reopen with ❓).
Sample plan library — 10 plans, basic → advancedNEW
2026-07-05
🏗 Samples now opens a gallery with thumbnails: studios → 1/2BR apartments → single-family 3BR, townhouse, L-bungalow → office suite, retail unit, 4BR penthouse. All CAD-exact, auto true-to-size, walkable in two clicks — modelled on a rentals/residential/commercial portfolio (IPM-style).
Walkthrough feel overhaulNEW
2026-07-05
Fixed inverted forward movement · wall collision with passable doorways · smart spawn in open space · ceilings, plank floors & depth fog · minimap click-to-teleport · fresh imports now fully replace stale models.
CAD Studio interfaceNEW
2026-06-21
Ribbon toolbar (File · Import · AI · Calibrate · Draft · Output), CAD status bar with live cursor coordinates in metres, dark model-space canvas, auto-dimensions on every wall, dynamic length input while drawing, Shift-ortho and endpoint OSNAP.
3D navigation suiteNEW
2026-06-21
Matterport-style minimap with player position, Floorplanner-style top-view toggle, on-screen controls help (?), re-center, and Shift-sprint in walk mode.
AI plan understanding
2026-06-20
🪄 Analyze reads walls, doors, windows, fixtures & printed dimensions from a plan photo; confidence colours + threshold slider; 🛋 AI furniture that fits with real clearances.
Multi-floor, stairs & pro exports
2026-06-20
Stack floors, 🪜 stairs, ▲▼ floor navigation in walk; 📋 measured report (PDF), ⬇ glTF model export, 📸 snapshots.
Hardening
2026-06-21
Whitelisted deploys (security), numeric-integrity guards on the scale cascade, GPU-leak fixes, non-blocking notifications.

  3. Calibrate → ↔ Measure two endpoints — OSNAP squares = exact picks
4 · Model in 3D BEGINNER · 5 MIN
  1. Output → 🧱 Model 3D, drag on the floor to draw walls
  2. Tap a wall with 🚪/🪟 to punch openings; tap floor with 🛋 furniture
  3. Set 🏢 floors, add 🪜 stairs, then 🚶 Walk and ride ▲▼ between levels
5 · Share, brand & export PRO · 3 MIN
  1. File → 🪪 add your name/logo, then ☁️ Share — the link unfurls branded
  2. Output → 📋 Report → print to PDF with room areas
  3. ⬇ glTF in 3D → open the model in Blender/SketchUp
6 · VR on any phone FUN · 2 MIN
  1. Open a shared tour link on your phone
  2. Tap 📱 Cardboard VR (works on iPhone), allow motion
  3. Drop it in any cardboard headset — tap to walk where you look

💡 Tips & shortcuts

Ortho lock — hold Shift while drafting to force perfectly horizontal/vertical walls.
OSNAP — hover near any wall endpoint: the green square means your click lands exactly on it.
Live dimensions — click DIM in the status bar to toggle wall length labels; the yellow readout follows your cursor while drawing.
Snap presets — click SNAP to cycle 1 m → 0.5 → 0.25 → FREE. CAD imports switch to FREE automatically to protect exact geometry.
Trust, but verify — after 🪄 Analyze, red walls are low-confidence. ↔ Measure them against the drawing before you build.
Sprint — hold Shift while walking to move faster through big plans.
Minimap — the top-right map in Walk mode shows where you are; ⟲ re-centers you at the spawn point.
Top view — in Model 3D, ⬒ Top snaps to a straight-down plan view (click again for perspective).

🧱 Build stages

Stage 1 — Accurate geometryIn progress

2D tracer · ✨ auto-detect walls (CV) · 📐 CAD import (DXF/SVG — exact geometry + automatic true-to-size from file units) · Sims 3D build · walk + WebXR + iOS Cardboard VR · ±2% scale gate.

Stage 2 — Furnished & texturedIn progress

Doors & windows ✓ · save/load + cloud share ✓ · OCR ✓ · furniture ✓ · room styles ✓.
Loop research re-prioritised: ✓ agent branding/white-label shipped (branded link previews + agent card + call/email). Next: lead-capture → measurement. Heavy realism deferred (barely moves share-rate per HBS; risks the instant-load moat).

Stage 3 — PhotorealisticPlanned

PBR materials · global illumination · time-of-day light · hero renders.

🔍 Research highlights

🧠 The moat = your dataset

Classical OpenCV.js tracer now; add ML wall-detection only once it beats it. CubiCasa5K is CC BY-NC — spike only, never ship. Build proprietary labeled data.

📐 Guard true-to-size

Whole product rides on scale → metres → geometry. Pixel-native model + one scalar + a hard ±2% release gate. Unified + OCR label-reader added.

📱 iOS as a feature

No WebXR on iPhone ever — ship stereoscopic Cardboard + capability tiers and market “works on any iPhone, no app.”

⚡ Perf wins

Cap setPixelRatio at 2 (DPR-3 phones drew ~9× pixels) and batch walls into ~3–6 draw calls. Pixel-ratio fixed.

🪄 AI plan understanding

Upload a plan → a vision model reads walls, doors, windows, fixtures & printed dimensions into an exact 3D model, then suggests furniture/appliances that fit (with clearances). ✓ Active & verified live.

🩺 Readiness audit (looped ×2)

23-agent audit, zero false positives. 62 → 68/100 after two fix passes. Applied: CAD-exact geometry, GPU-leak disposal, measure/scale-chip fixes, build gate, + numeric-integrity guards (Infinity/NaN scale rejected, DXF units, SVG distortion blocked), image cap, quota & CDN-timeout handling, error banner.
