# 2.2.2: 模型显示

共有三个运算器用于控制模型在Rhino视图中的显示方式：

|                      |                                                                     |
| -------------------- | ------------------------------------------------------------------- |
| **ModelView （模型视图）** | 设置常规显示属性。这些属性存储在模型中并持续有效，直到被下游的**“ModelView（模型视图）”** 运算器所覆写。 |
| **BeamView（梁视图）**    | 允许用户控制梁特定的显示属性。例如：将断面渲染为网格。                                         |
| **ShellView（壳体视图）**  | 包含壳体的显示设置                                                           |

图2.2.2.1显示了**“ModelView（模型视图）”**和**“BeamView（梁视图）”**运算器如何组合用于渲染梁的模型。单击运算器上的黑色项目标题可以展开视图运算器。在**“ModelView（模型视图）”**的**“Tags（标签）”**项下，默认情况下**“Elements（元素）”**复选框处于启用状态。这种情况下，可以显示元素中轴。**“Nodetags（节点标签）”**被激活后会显示节点编号。Karamba3D模型中的节点从零开始编号。该点同样适用于模型元素。有时通过**“Element Ids（元素标识符）”**显示其标识符会很有帮助。

在存在多个元素（多于一个元素）的情况下，若其节点重合，**“Assemble（模型构建）”** 运算器会将它们进行刚性连接。如果在建模中使用了不精确的几何体，则可能会导致意想不到的结果：尽管两个元素看起来可能是相互连接的，但实际上其节点位置可能并不精准。模型中的间隙通常会对其物理性能产生很大的影响。因为在一个地方会有两个节点编号，启用节点索引显示功能有助于用户找到此类间隙。

## Querying This Documentation
If you need additional information that is not directly available in this page, you can query the documentation dynamically by asking a question.

Perform an HTTP GET request on the current page URL with the `ask` query parameter, and the optional `goal` query parameter:

```
GET https://manual-1-3.karamba3d.com/chinese_1_3_3/2-getting-started/2-getting-started-1/setting-up-a-structural-analysis/2.2.2-view-the-model.md?ask=<question>&goal=<endgoal>
```

`ask` is the immediate question: it should be specific, self-contained, and written in natural language.
`goal` is optional and describes the broader end goal you are ultimately trying to accomplish on behalf of the user. GitBook uses it to tailor the answer towards what is most useful for that goal.

The response will contain a direct answer to the question and relevant excerpts and sources from the documentation.

Use this mechanism when the answer is not explicitly present in the current page, you need clarification or additional context, or you want to retrieve related documentation sections.
