在Illustrator中我们可以依据对象的属性 如：填充颜色、描边颜色或描边宽度来选择相同属性的对象，但是Illustrator中没有根据不同大小尺寸来选择对象的功能，下面介绍的就是根据大小尺寸选择对象的脚本。

1、下面是当前画板中的所有对象，我们想把一些在尺寸小一些的方形物体删除

2、运行脚本，在弹出的对话框中输入宽度和高度值，（其实只输入其中一个值也可）单击Select；

3、宽度和高度小于20.1的对象将被选中；

4、单击delete键删除对象；

//Select Paths By Size v.4.1.1.0 -- CS, CS2, CS3,CS4 (Change extension from 'jsx' to 'js' to run in CS)
//>=--------------------------------------
//   Selects all Path Objects, smaller/larger than given threshold
//   Only works for path and compound path objects.
//
//    If paths are selected, script runs on selected items only,
//    If nothing is selected, script runs on all paths in document.
//		::: Updates in V2 :::
//		• Rebuilt to select based on Size,  Area,  Width or by Height.
//		• Added "same size as" option
//		• If one object is selected, starts threshold at that size.
//		• Added Tool Tips
//		::: Updates in V3 :::
//		• Added status indicator
//		• Rebuilt processing engine so it's faster and more accurate
//		::: Updates in V4 :::
//		• Added  progress bar  (CS3 and above)
//	    • Speed increase
//		::: Update v4.1 :::
//		• Select by stroke weight (patched in 4.1.1)// /*   Notes:*/
