From left to right: Both options disabled, 从左到右: 两个选项都禁用,Flat Tree 平地树 enabled, 启用,Layers 图层 and 及Vertical Tags 垂直标签 enabled. 使能

The Flat Tree option removes all hierarchies (Object manger display only, not internally!) and lists all the items. This mode is especially useful when you are selecting many objects, such as when you want to assign them to a layer.

平面树选项删除所有层次结构(仅显示对象管理器，而不是内部!)列出了所有的项目。这种模式在选择多个对象时特别有用，例如当您想要将它们分配给一个层时。

The Layers option sorts the items into layer folders, where each folder is named after a layer in the scene and contains the items on it. Items not on a layer are placed in the Undef. Layer folder.

图层选项将项目分类到图层文件夹中，每个文件夹都以场景中的一个图层命名，并包含其中的项目。不在图层上的项目被放置在 Undef 中。图层文件夹。

You cannot directly copy layer folders to other scenes. As a workaround, select all objects on the layer (select the layer in the Layer Manager and choose Edit / Select From Layer) and copy them to the new scene. The objects’ tags are also copied. 你不能直接复制层文件夹到其他场景。作为一个解决方案，选择图层上的所有对象(在图层管理器中选择图层并选择编辑/选择从图层) ，然后将它们复制到新的场景中。对象的标签也会被复制
