Below is one way to create the codes you’re looking for in dynamo based on the subentities of the alignment. It uses nodes from the Civil3DToolkit (AlignmentExtensions.GetSubEntities and AlignmentSubEntity.SubEntityType) to get all the subentity types and then uses some string manipulation/logic to create the codes.

Dear Sir

Thanks a lots for your kind help. It works for me. Very Good Creative Thinking in the Graph :clap: :clap:
Sorry for the late response, because I took some time to understand your graph and replicate in my system.
