Step by step guide

Inside the Magic Eraser tool, there are two pages:

Indicate, using the painting tool, which part of your design you wish to delete.

Define creativity

Specify the level of creativity the AI should apply when deleting the structural part you previously defined.

  • Less creativity means the AI will follow a more precise and restricted approach, making minimal modifications and preserving the original structure as much as possible.

  • More creativity means the AI will take a more flexible approach, making broader modifications and potentially redesigning the area to blend seamlessly with the rest of the design.
