Inroads SS3 - export corridor linear features

Hi,

I'm trying to export the linear features created by the Corridor Modeling in SS3 to a standard DTM (with feature styles), specially cut and fill grade lines. I've tried creating alternate surfaces, and importing features into a standard DTM. The first option works halfway, I get most of the features (misses some benching lines), but the last cut/fill line get imported as a single element. Then I tried importing from the 3d model into the standard DTM file, even though the Cut linear feature is not continuous, It creates a single element drawing a straight line from the previous cut section to the next and so on, getting a haywire.

Any suggestions on how I can achieve this on SS3

thanks,
