Over time, drawings may accumulate many named objects that are no longer needed. For example, you may have a text style that is no longer used by any drawing text, or a layer that contains no drawing objects.
Purging named objects reduces drawing size. You can purge individual named objects, all styles and definitions of a [...]

By default, the boundary set consists of all objects fully or partially [...]
