SketchUp provides all the tools needed to keep everything organized. An organized model makes it easier to manage entities and control visibility. To get started, take a look at the following organizational features and techniques available in SketchUp:SketchUp提供了保持一切有序所需的所有工具。有组织的模型使管理实体和控制可见性变得更加容易。要开始使用，请查看SketchUp中提供的以下组织功能和技术：
Grouping Geometry分组几何图形 – Groups gather up multiple entities into one Object. Learn how to make a Group work in a model.组将多个实体聚集到一个对象中。学习如何让一个小组在模型中工作。Working with Hierarchies in Outliner在大纲视图中使用层次结构 – The Outliner is like a map to all the Groups, Components, and section planes in a model. The Outliner can help navigate around and identify Objects in large models, control visibility of Objects, and much more.大纲视图类似于模型中所有组、组件和剖面的贴图。大纲视图可以帮助在大型模型中导航和识别对象，控制对象的可见性等等。Controlling Visibility with Tags使用标签控制可见性 – Tags are a way to manage the visibility of multiple Objects in a model.标记是一种管理模型中多个对象可见性的方法。
What Happened to Layers?图层怎么了？ SketchUp’s Tags are an updated form of what was called Layers in older versions. Tags provide the same functionality that Layers provided and more.SketchUp的标签是旧版本中所谓的图层的更新形式。标签提供了与图层相同的功能，甚至更多。
Adding Dashed Lines to Tags在标签中添加虚线 – Further customize your Tags with dashed lines, changing all lines in the tagged Object from solid to dashed, giving that geometry a more specific meaning.使用虚线进一步自定义标记，将标记对象中的所有线从实线更改为虚线，为该几何体赋予更具体的含义。
