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.
