Hi @sascari
Yes, you have to download and install, since they are missing from your annotations folder.
Annotations are loadable families are created in external RFA files and imported (loaded) in your projects.
The below links represent the Family Templates, Project Templates and Family Libraries provided within the Revit 2018 product installation for all supported languages and locales.
To apply the content files:
- Download the desired content executable to a local location
- Launch the content executable from the saved local location
- Specify the desired content location (Default destination folder “C:\Program Data\Autodesk\RVT 2018”) and choose Extract.
