Adjust an object with Magic brush

Magic brush is available in the Create object preview. Use it to adjust the generated drawing before adding the object to your library.

1. Turn on Magic brush

Generate an object and select the wand button labeled Magic brush in the preview's upper-left corner. Draw directly over the preview with your pointer. Your guide appears in red.

2. Show the change you want

Use one clear gesture for each adjustment:

Your goal	What to draw
Remove a feature	A compact back-and-forth scribble over the feature
Move an edge inward	A simple line inside the existing edge
Extend an edge outward	A simple line outside the existing edge
Change several sides	A broad continuous line around the sides you want to reshape
Cut one area and extend another	A guide with clear sections inside and outside the current outline

For example, scribble over a lounger arm to request its removal. For a wider tabletop, draw the new outer edge and join it back to the existing surface.

The red line is an approximate guide. Champagne smooths small wobbles and tries to connect the edited section naturally to the surrounding drawing. A removal scribble selects the whole feature, including its detail lines. Removing a feature on a solid surface fills in the surface behind it.

Sample lounger with Magic brush selected, a red guide near the left arm, and Clear sketch and Apply changes buttons. — A red guide on the example lounger. Clear sketch lets you redraw the guide; Apply changes submits it.

3. Apply and review

Select Apply changes. Champagne reads the guide, edits the drawing and checks a rendered preview. It may make a correction during that check. The updated artwork appears when this process finishes.

Compare the updated outline with the change you intended. Check neighboring parts, gaps and surface colors as well. Use Undo edit to return to the previous successful version and Redo edit to restore it.

Useful controls

Clear sketch: remove the red guide and draw another one.
Cancel editing: stop the current request and keep your current preview.
Undo edit / Redo edit: move between successful artwork versions.
Create: accept the current drawing into your library.

Keyboard users can focus the editing area after enabling Magic brush. Press Space to begin a sketch, use the arrow keys to draw, and press Space again to finish. Escape leaves Magic brush.

When the result needs another pass

Apply one small change at a time. Use a compact scribble for removal and a simple continuous line for an edge. Keeping each guide focused makes the intended change easier to interpret.

An unsuccessful edit leaves the current preview available. Retry with a clearer guide or choose Regenerate object to start from a fresh drawing. The optional Classify brush intent control is explained in Settings and help.
