Alignment station offset label: profile elevation differences

[cwr001]

Hello,

this one was asked before but unfortunately never answered. (So I guess, as with many unanswered things, it can't be done.)

Still, is it possible to label the difference between two profiles (not surfaces!) in an alignment station/offset-label?

I want my "Height"-value to show "0.70".

Cheers!

Hi @cwr001 ,

Thanks for posting. 🤔

Looks like your 2nd profile is at a constant elevation? If yes, you can create an expression and the add a Reference text to the alignment label. See this screencast:

Otherwise, you will need to create a volume surface as discussed here.

Thanks for the reply - unfortunately they are not at a constant elevation so this kind expression won't suffice.

Next stop dynamo I guess! 🙂

I researched this type of situation in the past, and what I believe I came up with (in theory, and in some testing) is to  generate a surface from the profile, either by using feature lines to create a surface, or a corridor with a level section.  Just enough to give an actual surface under the alignment. then labeled the difference between the two surfaces.  We never actually used it on a real project, as the project manager caboshed the idea of trying to save time by attempting to automate the process.
