I am trying to convert some TINs that are in Microstation DGN files to ESRI raster format.

I wrote a script that converted the 3d polylines in the DGN file to an ESRI TIN then to a raster.  This worked great for about half of the files.

As for the other half, I can't even get the geometry to display in the ArcCatalog Preview window.  I can open the DGN files with the free Microstation Viewer app.  I can also use Data Interoperability Quick Import to pull the tin into a FGDB as polygons with Z values.  The problem with this is that when I try to use those polygons to build a TIN, it not only takes forever, only a very small slice on the right side of the tile is converted.

This really can't be that hard can it?  Any ideas on a better way to do the conversion would be appreciated.


PS - I have also tried Spatial ETL without much success.
