Auto Annotate alignment

I have a project where we are tying into existing bridges, so I had to create the alignment & profile myself based on the info in the PDF plans. I saw a video showing that you can auto annotate an alignment, but that method involved assigning a specific feature definition to the alignment which automatically annotated it. I do not have the feature definition available to me that they used in the video. Does anyone know if there is a feature definition that will auto annotate that is available in OBM, and if there is anything i need to do with settings to get it working? Or is there a better way to auto annotate? Thanks!
