An annotative dimension style still stores a DIMSCALE (100 in ACA
templates), but its features are sized by the annotation scale. Using
the stored value drew 3 mm dimension text 300 units tall, burying the
plan under giant digits.
Some templates also store their ratio scales already converted to the
drawing unit (a metre drawing's "1:50" as 1 paper = 0.05 drawing, with
CANNOSCALEVALUE 20). Applying the INSUNITS conversion on top shrank
the annotation multiplier a thousandfold.
