Civil 3D surface labels driving me nuts - are they worth the hassle or a waste of time?

I've been drafting site plans for about 3 years now, mostly in a small firm outside Nashville. For the longest time I refused to use surface labels in Civil 3D because I figured it was faster to just throw basic spot elevations on everything manually. My reasoning was simple - I can control exactly where each label goes and I don't have to fight with the software. But last month a senior guy at our office made me watch him set up a surface label style for a grading plan, and honestly the contour labels updated automatically when he changed the surface. That got me thinking maybe I was missing something. On the other hand, I've seen surface labels get totally jumbled when someone tweaks a surface boundary or adds a breakline, and then you spend an hour untangling them. So which side are you on - do you stick with manual spot elevations for control, or do you trust the surface labels to save time in the long run?

Have you ever tried using surface labels with a dynamo script to batch-place them based on slope or drainage paths instead of manually fighting with every single one? I set that up once for a big parking lot job and it cut my annotation time by a solid 40 percent because the labels only went where the math actually mattered. It's not perfect and you still need to clean up a few strays, but it beats jamming basic spot elevations everywhere and hoping they line up with the revised surface later.

Did you tweak the label placement rules at all so it didn't drop elevation points right on top of your catch basins? I tried a similar workflow on a site job last year and found out the hard way that the slope filter was grabbing all the subgrade drainage swales too, which made a mess of the cleanup. Ended up having to add a tiny spot elevation exclusion zone around my inlets to get it to behave. The time savings were real once I dialed that in though, probably around 30 percent on my end once the stray labels stopped piling up every time the civil engineer revised the grading.
