The Geometries Tree is a graphical control element that presents a hierarchical outline view of geometry items existing in the scene. Each geometry branch or node can have a number of subitems. This is often visualized by indentation in a list. A geometry can be expanded to reveal subitems, if any exist, and collapsed to hide subitems. The Geometries Tree allows the user to easily manage and navigate geometry objects.
As shown in the following image, the Geometries Tree is located at the left-side of the application window.
