When you add an annotative object to a drawing, the object will support only the annotation scale that is current at that time. In other words, the object has only one scale representation. To support additional annotation scales, you can add scale representations to the object.
In model space or in a layout viewport in paper space, you can display only the annotative objects that support the current annotation scale, or you can display all the annotative objects. You switch between these 2 options, respectively, using 
and 
on the status bar.
If you display all the annotative objects, those that do not support the current annotation scale are displayed using the annotation scale in which they were created.
Note: Objects that are not annotative but have annotative components, such as devices and air terminals, are always displayed and scaled according to the current annotation scale. They cannot be hidden using the ANNOALLVISIBLE system variable.
