The Viewer automatically hides objects based on predefined declutter zoom levels. This allows you to only see high-level information at higher zoom levels, removing small text and other items that are no longer readable at that zoom level. When an object is decluttered, any associated conditions and text will also be decluttered. The declutter option in enabled by default, but you can turn it off by unchecking the Declutter (On/Off) option in the Hide/Display dialog box.
