distributeStackedObjects.jsx

/////////////////////////////////////////////////////////////////
// Distribute Stacked Objects v1.1(and Center them too.)  -- CS,CS5
//>=--------------------------------------
// So you just imported 20 eps files and illustrator stacks them on top of each other. 
// You want to see them spread out a bit? Run this script.  
//
// This script distributes and centers all selected objects.  
// Each object's position is determined by it's stacking order in the layer palette.
// To adjust an objects position in the layout, 
// manually move the object's stacking order in the layer palette.
// The top object (in the layer) is always placed first.
//
// When the script is run, a prompt appears, 
// and the user can define a custom padding value for spacing the grid. 
// The script then auto-distributes objects, and centers them on the page.  
//
// This script was designed for creating artboards and for easy viewing 
// of a stack of imported artwork, but it should work with everything. 
//
// v1.1:Fixed a bug that crashed the script.
