The topmost object is created by doing parametric operations on objects which themselves were created by previous operations. By modifying the interior objects, the parametric operations propagate all the way to the top, generating a new result.

Objects that are deeper inside others are older, while objects that are outside are newer, and are derived from the older objects. Expanding and collapsing the objects in the tree view shows the parametric history of that object. In this case, the tree view shows this relationship by absorbing the older object inside the new object. Many operations create objects that are dependent on a previously existing object. The tree view allows managing the objects to keep them organized it permits creating groups, moving objects inside groups, moving groups inside other groups, renaming objects, copying objects, deleting objects, and other operations in the context menu (right click) which depend on the currently selected object and the currently active workbench. Working with the tree viewīy default, whenever a new object is created, it is added to the end of the list in the tree view.

The tree view showing various elements in the document. These objects don't necessarily have to be geometrical shapes visible in the 3D view, but can also be supporting data objects created with any of the workbenches. The tree view is a representation of the document's structure, and indicates what information is saved to disk. The tree view appears in the Model tab of the combo view, one of the most important panels in the interface it shows all user defined objects that are part of a FreeCAD document.
