Writing to Civil 3D Pipe Network

Hi,

The main reason is that we store all utility data (material, diameter, install date, disposal date, asbuilt) in the File Geodatabases, but would like to pass that data directly to the engineers who work in AutoCAD.

I have read sample Civil 3D pipe networks from the engineers to try to figure out how the data is set up, but I am still unsure of how to write the GIS data out so that the engineers have all the extra attributes.

Thanks!
