# 模型树

“模型树”提供了一种查看 FormIt 模型拓扑层次结构的方法。

通过转到“窗口”菜单并选中“模型树”旁边的框，来启用“模型树”。

在“模型树”中，由于每个“组”都有其自己的命令历史记录或“撤消/重做”堆栈，因此每个“组”都标识为“历史记录”。

在每个“历史记录”中，您会看到嵌套组、实例或几何对象（如实体）的列表。

还可以使用“模型树”查看附着到 FormIt 对象的非几何属性（字符串属性）。[可以使用 Dynamo 将字符串属性放置在由 SendToFormIt 节点创建的组上](https://formit.autodesk.com/page/formit-dynamo#dynamo-formit-nodes)。
