# 3.8.4: 剔除曲线 (Cull Curves)

![图3.8.4.1：根据线段的相互间距离细化的线段数据树](/files/-M9XuRdKpKBg-yb0077y)

诸如**“Line Results on Shells（壳体上的线结果）”**之类的运算器可能会生成密集的线状图案。**“Cull Curves（剔除曲线）”**运算器允许用户根据线段的相互距离来细化线段。**“C”**输入端口处需要一个数据树，其中的每个分支都包含构成流线的曲线段。**“LDist（极限距离）”**设置曲线段与不同分支之间的最小距离，在该距离以下的曲线段将被删除。接近程度是根据沿曲线段的等距控制点来确定的。默认情况下，每个线段使用三个点。点的数量可以通过**“NSamples”**输入端口来设置。

## 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_3/3-in-depth-component-reference/3.8-utilities/3.8.4-cull-curves.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.
