The Define Rules window allows you to define which elements are selected for a particular rule. Auto-numbering works by going through each element rule to collect the relevant drawings, and then applies the associated numbering rule to those drawings.

Input the name of the number rule in the Name field. The name must be identical to the numbering name in the Defined list of the window.
