You have two viewports at different viewport scales as shown in the exhibit.

Box 1 = annotative

an annotative dimension style is a dimension style that automatically adjusts the size of dimensions based on the viewport scale. An annotative dimension style has an icon next to its name in the Dimension Style Manager dialog box. The dimension style is annotative because the dimension text height is the same for both viewports in the layout, even though they have different viewport scales1.

Box 2 = associativeThe DIMASSOC is at its default value of 2, therefore the dimensions are associative because they are linked to and update with the measured geometry3.
