Introduction

The Outliner editor.

The Outliner shows the content of the blend-file in a tree. You can use it to:

• Get an overview of the data in the scene.

• Select and deselect objects.

• Make objects unselectable or invisible in the 3D Viewport.

• Exclude objects from rendering.

• Duplicate objects.

• Delete objects.

• Manage parent/child relationships and collections.

Items with an arrow on the left can be expanded. Click it with LMB to expand a single item, drag LMB to expand multiple items, or click Shift-LMB to expand an item recursively.
