Roadway section LumenRT

Hello,

I am currently using MicroStation connect version 14 with LumentRt and have seen many videos on the web where you take a 2d dgn file and bring it into google earth and export it to a 3d kmz file but this does not include the profile and superelevation of the roadway..

In my situation I have a typical roadway section 12’ tw and 8’ shld Lt and Rt side with a centerline profile and a superelevation and existing terrain data.(dtm) files in dwg and dgn.

How do go about adding this to a 3d dgn then importing this to LumenRT using Microstation Connect.or c3d.

Appreciate the steps to accomplish this.

Thanks
