# Prompt for design variations

> Render the same Rhino view as several facade designs at once from a list of prompts

Hold the geometry and camera fixed and vary only the design language. One list of prompts renders every option in a single run.

## How it works

1. **Linework view** is the Rhino capture all variations share.
2. **Design variations** is a text input holding a list, one prompt per design: glazed terracotta, pale brick with bronze, and so on. Each keeps the same opening: *Keep the camera and every edge of the building exactly as drawn.*
3. **Render each variation (Flux 3)** runs once per prompt. See [Data matching](https://docs.runchat.com/concepts/data/data-matching.md).

## Tips

* Flux 3 holds a line drawing's geometry most reliably, which is what you want when only the design should change.
* Ask an [Agent](https://docs.runchat.com/node-reference/nodes/agent.md) to write the variations, with its output format set to **List**.

## Use your own model

The image input holds a capture from our demo Rhino model, so the workflow runs as it is. To use your own model, open Rhino with the [Runchat plugin](https://docs.runchat.com/plugins/rhino.md) signed in, set up your view, and run the node marked **(optional) Rhino**. Then drag its screenshot into the image input. The scripts use only the standard display modes and match layers or materials by the keywords in their inputs, so they work on any model.
