Labelling 3D polyline with depth to surface on vertices.

Is there an efficient way of labelling up polygon vertices with an elevation difference to a surface? An example is to label up an underground service to indicate the depth below a design surface.

one way :make a surface from your polgon elevations , then a volume surface and  and labe the vertice referencing the volume surface 

Thank you

Thanks for the response. I was going that way but got put off by the point labels not ending up on the 3D polyline vertices but way below on the volume surface. But I do get one result I'm looking for: Sorting by elevation a list of points that do not have minimum depth.

You could create a Line Label (for use on Featurelines etc) that make use of an Expression you have set up to calclulate the difference between two selected Surfaces.
That way you get the Labels on your vertices and you don't have to create a TIN Volume Surface

Where would I create the expression that can get the surface elevations?

Hi
Go to Toolspace - Settings.
General - Label Styles - Line - Expressions

Create your expression.

Create your Line Label and include the Expression you have made.

Use the Label on your Feature Line.
Annotate - Add Labels - Feature Line - Multiple Segments...

What I'm trying to say is I don't find a surface elevation:-

Hi again,
I am sorry to have mislead you... 😕 This seems to only be available through the expression for Point Labels 😞

A not so great solution might be a heavy workaround.
- Create a TIN Volume Surface
- Create a Feature Line, draped to the Elevation of the TIN Volume Surface
- Create Labels (as discussed) using the Start Segment Z as value when creating the expression in the Label
