AI脚本建立点到点的连线教程

/////////////////////////////////////////////////////////////////
// All Points v.1.3 -- CS,CS2,CS3,CS4
//>=--------------------------------------
// This script simply draws a line from every point to every other point of your selected pathitem.
// Handy for making Mandalas. Try on polygons, stars or even freehand shapes.
