Erase a Part of an Object

The Eraser tool can remove a part of an object. This tool also works with groups and compound groups.

To activate the Eraser tool, tap on the Eraser icon in the Tools panel.

In order to erase a portion of an object, select this object. Then paint with the tool over the object's part that you want to remove.

If the original object has a closed path, the tool will keep it closed. So, the result will be one or several closed paths.
