How do we deal with changes to the base dgn after export to Lumen?

How do we deal with changes to the base dgn after export and population with trees and traffic in Lumen?  Do I have to start all over again?

  • Hi datkins,

    As long as the DGN and the LRT both have the same name you should be able to just export again from the DGN to update the exported content in the LRT file. Doing this should not effect your trees or traffic. 

    If you move the LRT file to a different folder and/or change the name of either the LRT file or the DGN file it won't work because the export always goes the default Scene folder (typically C:\Users\username\Documents\Bentley\Bentley LumenRT CONNECT Edition\Scenes) to a LRT file with the same filename as the source DGN. If the old LRT file is not found in that location with the same name as the DGN, a new LRT file will be created instead of updating the old LRT file.
