Closing a Dialog Box for User Selection
AutoCAD limits the number of nested dialog boxes to eight. For information on how to handle nested dialog boxes, see Nesting Dialog Boxes.
Insert an ellipsis (…) 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.
