Placing registration marks on the corners of document

Question

I have to process a lot of files to be router trimmed which requires them to have very specific registration marks.  There are 2 different marks we have to use.  The first mark is at the top left corner of the image contains 2 .25" dots separated vertically by a 1" gap.  The other mark is one .25" mark that is in the top right, bottom right, and bottom left corners.  I have both of these registration marks saved as symbols (or just AI files).  I want to be able to have the script automatically place the appropriate marks in the corners.  How can this be done?
Thanks!

Answer 1

here you go, your symbols must be the first and second in the symbols panel. Top/Left symbol must be the first in the Symbols panel. The other symbol must be the second in the panel
#target Illustrator
//  script.name = addRegistrationSymbols.jsx;
//  script.description = adds custom registration marks (saved as symbols) to each corner of the active arboard;
//  script.required = 2 symbols. Top/Left symbol must be the first in the Symbols panel. The other symbol must be the second in the panel
//  script.parent = carlos canto // 10/30/14;
//  script.elegant = false;

// usage: your symbols must be the first and second in the symbols panel.
if (app.documents.length > 0) {
  var idoc = app.activeDocument;
    var margins = 0;
    var bounds = idoc.artboards[idoc.artboards.getActiveArtboardIndex()].artboardRect;
    var ableft = bounds[0]+margins;
    var abtop = bounds[1]-margins;
    var abright = bounds[2]-margins;
    var abbottom = bounds[3]+margins;
    var twoDots = idoc.symbols[0];
    var twoDotsInstance = idoc.symbolItems.add(twoDots);
    twoDotsInstance.position = [ableft, abtop];
    var oneDot = idoc.symbols[1];
    var oneDotInstance = idoc.symbolItems.add(oneDot);
    var h = oneDotInstance.height;
    var w = oneDotInstance.width;
    oneDotInstance.position = [abright-w, abtop];
    var dup = oneDotInstance.duplicate ();
    dup.position = [abright-w, abbottom+h];
    var dup2 = oneDotInstance.duplicate ();
    dup2.position = [ableft, abbottom+h];
else {
    alert ("there are no open documents");
