Change the rulers original point to center of selected object

I am trying to write a JavaScript that changes the rulers orgin point to the center of the current selected object.

 

Here is my code:

var doc = app.activeDocument;
var sel = doc.selection;
if (sel.length > 0) {
var obj = sel[0];
var objBounds = obj.geometricBounds;
var objX = (objBounds[0] + objBounds[2]) / 2;
var objY = (objBounds[1] + objBounds[3]) / 2;
doc.rulerOrigin = [objX, objY];
}

 

It quits out on this line:

var sel = doc.selection;

 

Error:

Underfined is not an object

 

Can someone point me in the right direction.

 

Thank You

Hi @m1b , @pixxxelschubser , @femkeblanco , @CarlosCanto ,

 

Thanks for the help. But I over thought this in needing a script for the task. I was able to do it using actions.

 

Thanks again.

I would rather replace this line:

var objY = (objBounds[1] + objBounds[3]) / 2;

 

replace with this line:

var objY = (objBounds[1] + objBounds[3]) / 2 -doc.artboards[doc.artboards.getActiveArtboardIndex()].artboardRect[3];

Hi @Deprive, it looks like you probably have this covered, but I wanted to chime in myself, because, strangely, none of the scripts/modifications you guys @femkeblanco@pixxxelschubser mentioned actually work on my system (Mac OS 13.1, AI 27.2). They just don't move the ruler origin—nothing happens.

 

Here is what I do and works for me. I really do not understand what I'm doing in part of this script, but since it works, I figure I can post it! (Also @pixxxelschubser I am laughing when I post this because you may be appalled by how much of a long process I make something so simple, haha, but that is just how my mind and system works 🙂 ).

Well done @Deprive on solving it. Are you able to post the action for others?
