I've used Inroads for 25+ years and I can't find any command that allows me to annotate stationing of my centerline. I have a complete corridor built but can't do this SIMPLE task inn ORD Connect U4.
To annotate an alignment, you need to make sure that a Feature Definition is assigned. The Feature Definition controls the annotation. You can annotate by going to Drawing Product > Element Annotation. This wiki can help: https://communities.bentley.com/products/road___site_design/w/road_and_site_design__wiki/34981/video-editing-the-station-format-of-a-horizontal-alignment-s-annotation. We also have training from our LearnServer that would be helpful as well. https://communities.bentley.com/products/road___site_design/w/road_and_site_design__wiki/33436/openroads-designer-connect-edition-training-links. https://communities.bentley.com/products/road___site_design/w/road_and_site_design__wiki/36305/what-is-an-annotation-group.

I can find NO documentation in the online help on how to define an Annotation Group or assign it to a feature definition!
