Turning MicroStation 3D line work into InRoads SS4 Civil Features

Looking for a workflow that will allow me to do the following:

1) Take 3D line work that was generated in MicroStation and create an InRoads SS4 civil feature from it. (Ex: Utility company provides 3D line work, and want to "import" it into the dgn as a 6" gas line civil feature)

2) Generate a set of cross sections that displays the newly imported 6" gas line.

Seems simple enough and something that really should be basic to do since it occurs frequently within a typical project workflow, right?
