# Settings and help

Choose optional drawing settings and recover from common generation, editing and import problems.

The default settings are a starting point for creating objects. Open **Expert mode**
in the **Create object** dialog when you want to change how the artwork is generated
or how brush guides are interpreted.

## Drawing settings [#drawing-settings]

| Setting                   | What it does                                                                         |
| ------------------------- | ------------------------------------------------------------------------------------ |
| **Generation model**      | Chooses the service that draws the initial object: GPT Image 2.5 Sunburst or Flare   |
| **Auto-lines**            | Controls how the drawing's dark outlines are converted into shapes                   |
| **Brush model**           | Chooses the assistant that interprets your guide and adjusts the drawing             |
| **Thinking effort**       | Sets how much reasoning the brush assistant can use; higher settings may take longer |
| **Classify brush intent** | Adds a separate gesture-reading step before the brush assistant edits the drawing    |
| **Show more information** | Shows extra progress and timing information for the request                          |

The initial UI settings use **Sunburst**, **Auto-lines** enabled, **Gemini 3.8 Flash**,
**Low** thinking effort and **Classify brush intent** disabled. With classification
disabled, the brush assistant reads the guide and edits in one workflow. Enabling
classification adds a first assistant that chooses the type of change.

See [How vectorizing works](/fr/ai-flows/vectorizing#what-auto-lines-changes) for the
effect of Auto-lines on the finished drawing.

## What happens to your instructions? [#what-happens-to-your-instructions]

Your object name tells Champagne what to draw. The app adds instructions for the
top-down view, colors, outlines and empty background. For Magic brush, your red
guide tells it where and how to change the current object.

During an import, Champagne repeatedly looks at the image, places shapes, checks
the result and corrects the draft. You see these activities through the progress
labels and the updating preview.

Names, artwork and plan images are sent to the configured AI services for
processing. Use images that your organization is comfortable sharing with those services.

## While a request is running [#while-a-request-is-running]

Generation and editing can take several minutes. Keep the preview open while the
request runs. **Cancel generation**, **Cancel editing** and **Cancel import** stop
their respective requests.

If you want more detail, enable **Show more information** before starting the
request. Progress may include drawing, vectorizing, editing and inspecting the result.

## Common problems [#common-problems]

### The drawing looks different from what I expected [#the-drawing-looks-different-from-what-i-expected]

Use a more specific object name, then select **Regenerate object**. Describe the
main shape and any essential feature. Use Magic brush when you want to keep the
current drawing and change one part.

### The brush changed the wrong part [#the-brush-changed-the-wrong-part]

Choose **Undo edit**. Draw a smaller, clearer guide and apply one change at a time.
Use a compact back-and-forth scribble for removal and a smooth line for a new edge.

### The lines or small details look rough [#the-lines-or-small-details-look-rough]

Try another generation with **Auto-lines** enabled. A simpler subject with fewer
tiny details may give a clearer result. Review the object at its expected size on
the plan as well as in the enlarged preview.

### A request failed or timed out [#a-request-failed-or-timed-out]

Use the error notification's **Retry** action when offered. For a generation,
you can also choose **Generate object** or **Regenerate object** again. If the
message mentions a spending limit or an unavailable service, ask your administrator
to check the AI service configuration.

### An imported draft needs corrections [#an-imported-draft-needs-corrections]

Read the review notes and compare walls, openings, furniture and spacing with the
source image. Choose **Use draft** and make the adjustments in the editor. For a
fresh attempt, upload a clearer or more tightly cropped image.

### I want to leave without saving the layout [#i-want-to-leave-without-saving-the-layout]

Use **Discard changes** in the floor-plan editor. A library object you already
accepted with **Create** remains available in the library. Save the layout with
**Save plan** when you are ready to keep the placements.
