1)SD、ED 曲线头尾端的清除距离

2)产生方法 有点数、公差和最大距离、固定距离、Meash 四种方式。每种设置搭配不同的方法产生测点的分布情况会不同。

点数+等距离：沿曲线等距离分布固定数量的测点。

点数+等曲率：按曲率分布测点，曲率大的地方点密集，小的地方稀疏，总点数固定。

公差和最大距离+公差+最大距离：按曲率分布测点，曲率大的地方点密集，小的地方稀疏。公差值越小，整体的密度越大，最大距离控制测点间的最大间距，点数不固定。

固定距离：按照设置的间隔等距离分布测点。

Mesh+偏向值：按曲率分布测点，曲率大的地方点密集，小的地方稀疏。偏向值控制整体的密度，越小整体的分布越密集但必须在0.02~50之间。

3)参考元素 

可拖放元素或数模，生成测点的方向会垂直于参考元素，如3D曲线需要用数模做参考才能生成测点。

4)深度和偏移 

偏移：测点沿矢量平移指定距离。

深度：2D曲线在设置的深度位置生成测点。
