I'll add this new piece of information to the puzzle. When I right click on the label that remained in the profile I get the typical menu (edit structure, style, etc.). If I edit the structure properties, change the surface, hit apply (nothing), then change rim adjustment to false, hit apply, the manhole shows up. Go back to my other surface, gone. I tried all the combinations I could think of ... adjusted sumps, surface values, etc using the surface I want to use. Nothing, nada, zip, zero, zilch. What do these manholes have against that surface? Why when I delete the manhole and replace it with a new one, it doesn't show up either. Other manholes in other networks play nice with that surface. Can anyone tell me why the manholes in this network are not playing nice with my surface?
