Even the annotation visibility is on, when you use the PDF out to convert from cad to pdf, the output does not show the objects that are annotated scale. Its like the annotation visibility is off although its on. This is a serious bug as when you are converting your cad files to pdf and ready to submit you do not realize that there are some objects missing.
