# 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。
