Same artboardRect, different positions

[iLLMonkey]

I've been scratching my head over this seemingly simple task. I just want to create a new document with the same artboard as my current document. I'm using this code:

function main(){
    // Document Reference
    var doc = app.activeDocument;

    // Current Doc artboardRect
    var abRect = doc.artboards[0].artboardRect;

    // Create a new document
    var newDoc = app.documents.add();

    // Set new document artboard to abRect
    newDoc.artboards[0].artboardRect = abRect;

}
main();

The size looks right but the artboard is slightly offset from the original (original to the left):

The first document has a pageOrigin of [194, -896] which is also the exact ammount that the "new" artboard is being offset by so it feels I'm getting closer to solving this. BUT, it doesn't matter if I set the first document to [0,0] or the new document to [194, -896], it still gives me the same result for some reason.

Hi @iLLMonkey, does this help?

function main() {

    // Document Reference
    var doc = app.activeDocument;
    var rulerOrigin = doc.rulerOrigin;

    // Current Doc artboardRect
    var abRect = doc.artboards[0].artboardRect;

    // Create a new document
    var newDoc = app.documents.add();

    // Set new document artboard to abRect
    newDoc.artboards[0].artboardRect = abRect;

    newDoc.rulerOrigin = rulerOrigin;

    $.writeln('doc.rulerOrigin = ' + doc.rulerOrigin);
    $.writeln('newDoc.rulerOrigin = ' + newDoc.rulerOrigin);

    $.writeln('doc.artboards[0].artboardRect = '
        + doc.artboards[0].artboardRect);
    $.writeln('newDoc.artboards[0].artboardRect = '
        + newDoc.artboards[0].artboardRect);

    // now matcht the *views*
    var docView = doc.activeView;
    var newDocView = newDoc.activeView;

    // match the new doc view
    newDocView.zoom = docView.zoom;
    newDocView.visibleZoom = docView.visibleZoom;
    newDocView.centerPoint = docView.centerPoint;

    $.writeln('docView.bounds = '
        + docView.bounds);
    $.writeln('newDocView.bounds = '
        + newDocView.bounds);

};

main();

That gives you a couple more things to play with to match your original document. There might be other things that need to be matched in the new document also. If matching the document is really important, another approach could be to duplicate documents File object (doc.fullName) and open it (and remove whatever you don't want in the new doc).

Thanks @m1b Unfortunatly it didn't help. I've tried alot of different values. Strangely enough the properties below can all have the exact same values in two different document and still produce two different artboard placements:

pageOrigin
artboardRect
height
width
geometricBounds
cropBox
rulerOrigin

Am I missing any properties that could affect the artboard placement?

It gets weirder. if I create a rectangle the same size as the artboard in doc and .duplicate() it to the newDoc it gets placed exactly as I want it. This is a potential fix since I could just conform the artboard to the rectangle. But I still want to know why this is 😃

It think this is because documents.add() adds a document with whatever default width and size, with the origin (0, 0) being the lower left corner of the document.  Any change to the origin will be in reference to that lower left corner.

Interesting. I can't reproduce that issue. Can you share a demo .ai file? You can attach it here if you save as pdf with ai editing.
