Harold, you speak as if there is another way to set center mark size. Is there? The setting shown above in File Properties/Annotations seems to be a one-size-fits-all setting, and when you click on Apply, the whole drawing appears to be updated to the new setting. For flexibility and for clarity of visual drawing presentation, I would like to be able to adjust center mark and centerlline size, primarily meaning the extension distance beyond the drawing entity, for each mark or line on an as-required case-by case basis. Is that kind of flexibility not available?
