Convert Civil 3D Styles with Dynamo
Stephen Walz demos a basic Dynamo for Civil 3D script for some simple Styles Standards conversions.

This sort of Style Standards converstion will continue to get easier in Civil 3D as Dynamo gets more supported Nodes.
Via custom Python code blocks and the Civil 3D API you can get to and update more types of Styles.
Needless to say, the order of the Style Tuple processing also grows in complexity and importance.
