Joe, I think that this should be pretty close to what you want. It looks for path items in the selection, then should check to see if its a rectangle if it is then inset guides 3mm. I think it needs a check for right & left direction control points but I have NOT the time at the mo.
#target illustrator
var docRef = app.activeDocument;
// Convert mm to points
var thisOffset = 3 * 2.834645;
with (docRef) {
// Get selected items Array
if (selection != '') {
for (var i = 0; i < selection.length; i++) {
// Check if its a path item
if (selection[i] instanceof PathItem) {
// This might need a better test!!!
if (isRectangle(selection[i])) {
// Ignore any stroke values
var thisPath = selection[i].geometricBounds;
// Calculate guide box
var guideTop = thisPath[1] - thisOffset;
var guideLeft = thisPath[0] + thisOffset;
var guideWidth = (thisPath[2] - thisPath[0]) - (thisOffset * 2);
var guideHeight = (thisPath[1] - thisPath[3]) - (thisOffset * 2);
// Make new rectangle
var myGuides = pathItems.rectangle(guideTop, guideLeft, guideWidth, guideHeight, false);
// Make it guides
myGuides.guides = true;
} else {
alert('A Path Item was NOT a rectangle?');
} else {
alert('An object was NOT a Path Item?');
} else {
alert('You have NO selected objects?');
function isRectangle(pathObject) {
with (pathObject) {
if (pathPoints.length != 4)  return false;
if (pathPoints[0].anchor[0] != pathPoints[3].anchor[0]) return false;
if (pathPoints[1].anchor[0] != pathPoints[2].anchor[0]) return false;
if (pathPoints[0].anchor[1] != pathPoints[1].anchor[1]) return false;
if (pathPoints[2].anchor[1] != pathPoints[3].anchor[1]) return false;
return true;
