(bear with me here as it sounds scary)
But.. when I was at an Architecture firm, we used a DWG linked into the project template from our “R” (Resource) drive.
-take a breath-
This DWG just had text in it and was linked into the starting view only. It had no other elements and was just used for “BIM Broadcasts”. Stuff like updates, new content, training announcements, etc.
Why a DWG?
It was Revit version agnostic. We were able to maintain one file, and it worked across all supported Revit versions.
Previous to that, we used an RVT and had to have a version for each Revit version. Which was harder to maintain.
This also meant that updating an “announcement” was relatively simple. I only had to update one file, and every project that started with the template would be connected to that file.
This was nice because always running a Dynamo graph will never happen consistently at any scale (unfortunately).
*Note: I am not suggesting that this is the best way to do this, just thought I would share
