You can create a generic annotation family or load one from the available annotation families in the 
  Revit LT library. 
 This procedure uses an existing annotation family. 
Note: Though this procedure uses specific family files, the steps are common to any generic annotation you may want to add to a model family.

Open
Family. 
 
-  Open the microwave.rfa family from the Specialty Equipment\Domestic folder in the Imperial library. 
  
Metric users: The microwave from the Metric library is in the same folder and is called M_microwave.rfa. 
  
 
  Note: For international users with localized versions of the product, family names and paths may be different than those specified in this procedure.
