Civil3D place a leader with extended property data

Hello all,

For my next script I’m trying to place a leader with my featurelines.

I’m searching for a package which can help me with this. I’ve been searching the web for some time now, but only found information about tags for Revit, but I need this for Civil3D.

Does anybody have an idea which package I could use?

Many thanks in advance.

Kind regards,
