生成螺旋形的球体线条，还有经度线，乱线三种效果

用于快速炸开选定的样条曲线，将线条元素炸分为单独的对象。A small tool for quickly exploding all selected splines and shapes elements into separate objects. Support for turning on and off Undo for speeding up the process.

Additional Info: Just select 1 object and animate it, after that click "start buttonn" and you will get unimated growth spline Version Requirement: max7

SplineSurface is a small tool that creates a quad surface based on 4 spline shapes. Usage Pick up your 4 splines, set the number of subdivisions and click on Build Surface. You can reverse the order of each shape with the "R" button. Version Requirement: 2010 - 2016

创建各种样式的箭头。Arrow spline primitive, useful as a control object in rigging. Works only in 3ds max 2016 SP2 and higher.

超级螺旋，示例的是螺旋风管，螺纹，金属软管，环形坡道等的制作方式，可以支持自定义形状。Example usage would be spiral ductwork, screw threads, flexible metal tubes, circular ramps etc. No smoothing groups are assigned, for smooth look either use Smooth modifier or add points to the spline profile.

这是一个二给图形线条的创建，方便用来制作皮带轮子图形，以及辅助动画。创建的线条，可以直接打可渲染显示，制作滑轮履带的路径动画。 Technically you can probably call it a rounded isosceles trapezoid but it will be more useful as a base for path of bicycle chains or pulley belts. When both radii are the same and spline set to renderable, it could also be used as a simple chain link.

用来反转面，反转法线，反转线条首尾。Flip normals of polygons or objects Flip (Reverse) splines

small tool which creates cross-section splines of one or several objects in the scene.

或许，这是个然并卵的功能，用来一键生成三个正交的圆形线条。This plugin creates a new Spline primitive called "Orb". It can be used to quickly create orb controls for use in rigging, for example.
