Linking dynamic labels to text fields

[connermLUVQ3]

A little background - I am working on grading multiple curb ramps for a project. Our plans are required to contain all ramp slopes/spot elevations within a table rather than shown on the actual ramps. Rather than do this by hand, we want to use feature lines to grade the ramps, wings, and landings. 

I'm thinking I'd like to put dynamic surface labels on a no-plot setting, and have the table contain fields which are linked to a specific dynamic label. That way, if I change a feature line grading, the dynamic, no-plot label will update automatically which will cause the field to update automatically. Is there a way to do this? If not, any other suggestions? Thanks in advance

I think this is more of a  C3D question but as I don't follow that forum, here is my best. This is something Autocad guys could use as well.

I don't see that those two objects will present their data in a field. I thought maybe you could constrain a symbol to a feature line but that does not seem the case either.  You can insert blocks that would yield that information but they wouldn't be dynamic. However you could use the dynamic labels as a visual check to compare data after editing.

If your looking for a table that will autofill then I would make a block with an attribute for the ramp id. You could then have someone place the elevation blocks by snapping to your feature lines.  Using Dataextraction a table with x,y,z values, ramp id and formula column for the slopes could be made. the x,y value columns can be hidden. This would be somewhat dynamic in that once you finish your surface you could use the block to surface feature to update the data and then the table would update.
