# Refine a Design Through Natural-Language Changes

| Epic | Delivery status | Status source | Owner | Approved for Solution |
|---|---|---|---|---|
| `3DARCH-EP-9` | `IN_BACKLOG` | `DERIVED` | 3D Architecture Wizzard team | No |

## Goal

Apply focused natural-language changes to a saved apartment and present the updated 3D result while preserving project identity and unaffected content.

## Benefit

Design refinement becomes a conversational loop that keeps the spatial model valid and reviewable.

## Problem or opportunity

A person needs to iterate on a generated design without directly manipulating geometry or editing scene files.

## Constraints

- Only materially implemented legacy behavior is included; planned-only capabilities remain outside the approved catalogue.

## Features

- [3DARCH-FT-30 — Apply and persist a natural-language design change](./3darch-ep-9/features/3darch-ft-30.md)

These Features are approved for documentation only. Each remains outside Architecture solution work until a separate human **Approved for Solution** decision is recorded.
