We recently upgraded from ArcGIS 10.1 to 10.3. Before the upgrade, opening Microstation DGN files would display line work in a 3-color scheme that we use for hydrographic survey depths (there are no other features in the drawings except for lines and annotation). The correct colors would display without making manual adjustments. Now, in 10.3, the colors displayed are random.
I know that I can manually adjust the colors and achieve the same result. However, this was not necessary in our 10.1 setup. I also don't remember if customizations had been applied to make this possible in 10.1 (custom style file that is automatically applied?, modified normal.mxt?, etc.)
Does anyone have insights how to, either,:
1. prevent the Microstation color table from being misread when adding a DGN into ArcGIS?
2. enable an ArcGIS customization that automatically maps DGN layers to defined colors?
