Hard to tell for sure, but the first thing I would try is adding the DV file's path to MS_RFDIR.
I logged this back in January.
The files must all be in the same directory. I've amn example posted in this forum http://communities.bentley.com/products/building/building_analysis___design/f/5917.aspx
The nested filed don't show and only annotations do.
I have made sure that my reference variable points to all directores with the files that are referenced. DEM fiels work fine but the BV's cannot be seen.
