Annotations in CAD drawings are given fixed sizes so that CAD application
will generate the annotations at the fixed size even though modeled
objects within the CAD drawing are scaled in accordance with a paper
space scale selected by the CAD designer. The annotations generally
comprise text annotations and graphic annotations, including one or more
of text, dimensions, hatch patterns, and symbols, and are represented as
annotation objects having multiple properties, such as size, visibility,
position and rotation.
