Add Profile View Station Elevation Labels

Civil3D
2

Hi @lebinhx3c2012 ,

I’m not aware of any packages that would do this, so we need to use the methods available in the API. Here’s some Python code to try (it’s a bit verbose - sorry). This will create labels and override text components for offset, northing, and easting (since those aren’t available to add to a text component by default).
