## Prompt · Simplified Chinese

```text
将上传2D两房平面图转换成3D轴测建筑图，保持外轮廓、偏左隔墙、隔墙门、右房底边入户门和顶边两扇窗位置与比例。墙体统一拉伸高度，无屋顶，蓝图深蓝背景、浅蓝实体和白色细边线、柔和环境遮蔽。相机从平面图下边偏右的方向俯视，能看到两房内部，无家具、无文字。4:3。
```

## How to use

Copy the exact prompt used for this image. Changing the subject creates a new, untested variant. Upload the ordered synthetic reference images shown in the run before generating.

## Observed result

Two rooms, the offset divider, two windows and both doors correspond to the plan. This is the first generated view; the separately recorded reverse-view step uses this image as its input.

## Source

Independently adapted from the supplied design prompt collection, case 42. [Source](https://github.com/qzh3722/awesome-nano-banana-spatial-design/blob/main/README.md). GPT Image returned no precise version identifier.

## Reverse view

Use the first output in the [second-step template](https://promptseen.dev/en/templates/design-top60-42-reverse-template/). Both runs preserve their own actual prompt and reference image.

- Template v1: [Reverse an axonometric viewpoint](https://promptseen.dev/en/templates/design-top60-42-reverse-template/)

What we saw: Second step: the large room is now on the left, the small room on the right, windows near the camera and the entrance on the far side. This is a generated spatial concept; exact geometry and lighting conservation are not guaranteed.

Prompt used for this print:

```text
以附图中的蓝色两房3D建筑图为唯一场景。只把相机绕建筑的竖直中心轴旋转180度，保持俯视角与焦距。所有墙体、隔墙、门、窗、材料、世界空间光照与阴影不变，不新增物件。反向视角应使原来的小房间在画面右侧、大房间在左侧；原顶边的两个窗在近侧，原入口门在远侧。不要水平镜像图片；生成真正的反向三维视角。4:3。
```
