.AutoCAD limits the number of nested dialog boxes to eight. For information on how to handle nested dialog boxes, see
Insert an ellipsis (â€¦) in the label of a button that displays a nested dialog box unless the nested dialog box is an alert box. Don't nest dialog boxes more than three deep. Four levels of nesting are reasonable if the fourth-level dialog boxes are only alert boxes. Because dialog boxes appear initially in the center of the screen, make the nested dialog boxes smaller than the main dialog box.
