The properties that can vary per scale representation depend on the object type. Each scale representation may also have different values for positional properties, such as a text string base point. Scale representations allow annotative objects to be drawn at different sizes based on the annotation scale. Scale representations allow for the display of the same annotative object differently in different paper space viewports at the same time. However, as you zoom in or out of a viewport with your mouse wheel or by using the Zoom commands, the viewport scale updates while the annotation scale will remain unchanged. For example, when you change the viewport scale, the annotation scale updates to match the new viewport scale.
The viewport and annotation scales are synchronized when the annotation scaling controls are used. If multiple scale representations are supported, the annotative objects in the viewport are drawn and scaled based on the annotation scale without affecting the scale or display in the model tab or in other paper space viewports. When working in a paper space viewport, the annotation scale of the viewport controls the scale of the annotative objects created in the viewport.
