# Walk through the apartment at human scale

| Feature | Parent Epic | Delivery status | Status source | Owner | Approved for Solution |
|---|---|---|---|---|---|
| `3DARCH-FT-29` | [3DARCH-EP-8 — Review and Walk Through a Generated Design](../../3darch-ep-8.md) | `IN_BACKLOG` | `EXACT` | 3D Architecture Wizzard team | No |

## Description

Enable a person to enter near the detected apartment entrance, look around, move through rooms, and return to overview mode.

## User or operator problem

A person needs to experience the generated apartment at human scale and return predictably to overview review.

## Expected value

Enables experiential validation of circulation and scale beyond a top-down overview.

## Scope

Includes entrance detection, valid walk-mode start, pointer look, WASD movement, collision boundaries, and return to Orbit mode.

### Exclusions

- Editing, export, VR review, and collaborative walkthrough are excluded.

## Acceptance outcomes

- [ ] Walk mode starts at a valid position just inside the detected entrance.
- [ ] Pointer look and WASD movement provide a human-scale review.
- [ ] Collision prevents movement through walls and solid furnishings.
- [ ] Escape or the visible mode control returns predictably to Orbit mode.

## Dependencies

- [3DARCH-FT-28 — Inspect the apartment from an overview](./3darch-ft-28.md)

## Risks

- Legacy Walk mode has no collision enforcement and permits movement through walls or furniture.
