I upgraded to OpenRoads ConceptStation version 10.00.13.36. When I open my dgndb that was created in the previous version in this 10.00.13.36 version, my terrain or 3sm file shifts vertically around 40-100 units up. How do I fix this?
Answer for 10.0.14 and newer
1. Open the DgnDb file
2. Go to the Information page of your project, this is the second to last entry accessible from the left backstage menu
3. Use the Terrain Vertical Datum dropdown box to change the value from "Geoid" to "Ellipsoid" and then hit the Save icon
Answer for version 10.0.13.36:
Before beginning, make a backup copy of your .3sm file. The workaround is to download/install the DB browser for SQLite and edit the GCS text.
Launch the DB browser for SQLite
Go to File > Open database and open the .3sm file
Go to the Browse Data tab
See the red arrows in the screen capture below
