Has anyone successfully converted a v7 dgn file to a v8 file using a .csv file? I have tried exporting the latest level setup from a seed file I created with still no luck. Any Suggestion??
I gave up as well. I found it is easier to just to use selection sets and change symbology. It's the longer way but the safe way. If you use InRoads for planametric mapping, you can try to change your DTM to a feature based model then display it as mapping.
