Acrobat 3D - Resizing 3D Area Programmatically with JavaScript - Setting Annot3D.rect Not Working

[lucasp76202610]

I have a PDF that is displaying a 3D object. There are some other fields that I would like to hide/show/relocate on the click of a button and expand the 3D area to maximize the viewer size. The Annot3D object exposes a rect property similar to a property that fields/buttons expose. When trying to set the rect property on the Annot3D object, it does not resize. I follow this same process when resizing/relocating fields and buttons and it works just fine. I have confirmed in the documentation that the field is both readable and writable. If I select the frame while using the "Prepare Form" tool, I can resize it manually, but that does not work for my use case - it must be done programmatically. See below code sample - the code works for altering the display state of the list box and the placement of the button, just not the sizing of the Annot3D object. This code lives in a MouseUp event for the button.

var a3d = getA3d(this); // returns Annot3D object
console.println(a3d.rect);

var collapseExpandBomButton = this.getField('Collapse_Expand_BOM');
var bomListBox = this.getField('BOMListBox');

var buttonRect = collapseExpandBomButton.rect;
var bomRect = bomListBox.rect;
var a3dRect = a3d.rect;

switch (bomListBox.display) {
    case display.hidden:
        // display it
        bomListBox.display = display.visible;

        // update button placement
        var buttonHeight = Math.abs(collapseExpandBomButton.rect[1] - collapseExpandBomButton.rect[3]);
        buttonRect[3] = bomListBox.rect[1];
        buttonRect[1] = bomListBox.rect[1] + buttonHeight;
        collapseExpandBomButton.rect = buttonRect;

        //update 3D space placement
        a3dRect[2] = buttonRect[0];
        a3dRect.rect = a3dRect;

        break;
    case display.visible:
        bomListBox.display = display.hidden;

        // update button placement
        var buttonHeight = Math.abs(collapseExpandBomButton.rect[1] - collapseExpandBomButton.rect[3]);
        buttonRect[3] = bomListBox.rect[3];
        buttonRect[1] = bomListBox.rect[3] + buttonHeight;
        collapseExpandBomButton.rect = buttonRect;

        //update 3D space placement
        a3dRect[2] = buttonRect[2];
        a3dRect.rect = a3dRect;

        break;
}
