Question:
How to synchronise the different standards I have in my existing dgn files when the libraries have been modified?
Answer:
Since the release 2020R1, 10.08.00.88, it is possible to synchronise the different standards you have in your existing dgn files with the libraries, DGNLib files.
In the Project Explorer, go the OpenRoads Standards section then expand the Standards and right click on the name of your file.
And click on 'Update Standards From dgnlib'.
