Hi Jens,
Find attached the Grasshopper file used in the Elevation mark in VisualARQ templates. I’ve divided the elevation by 1000, so it will show up in meters in your mm document, when you create a new annotation from it (or you can update the existing one “Elevation mark”. In that case, do right click on it and select “Edit…”).
