NestedDrawings represents a collection of drawings attached to an attached drawing.

The NestedDrawings collection is contained by the AttachedDrawing object, which is contained by a DrawingSet collection.

You cannot examine the objects of this class if the parent object is not active. Check the AttachedDrawing.Active property before trying to get the NestedDrawings object from the AttachedDrawing object.

You can use a NestedDrawings collection if you first attach a drawing, which has attached drawings associated with it, to a project, and then attach other drawings to that AttachedDrawing object by using a NestedDrawings collection.
