Problem Description: If we want to change the Annotation Scale while being in DWG Mode, How can we do it ?
Any changes to the annotation scale while in Dwg mode will not be saved into the Dgn. This operation should be done before saving the Dgn file to a Dwg file.
If you export the Dwg file to a Dgn, then you can change the annotation scale with no issues. Otherwise, when you open the Dwg file, it will remain with the original annotation scale.
