Hello,
In the Project environment, reading a title block family, am trying to edit a Family type, parameter, governing the visibility of Generic Annotation Families.
What hapens when you skip the “<Generic_Annotations>” part in your Code Block.
In the upper picture the name of your parameter is only “BH_Keyplan”
@MJB-online is right lose the “Generic Annotations”, and feed Element Type into Value input, Element name just wont work, because this parameter type expects Element type as Value.
