My DGN does not list that I have any models. It appears blank, but I have models in the file. How do I recover the list within the model dialog box?
Open the Key-In under OpenRoads Modeling > Home > Primary and type MODEL REINDEX and hit Enter. It will reindex the model, and the models that are there should now be listed. Also see this wiki that describes another functionality of this command as well: https://communities.bentley.com/products/microstation/w/microstation__wiki/13894/cannot-delete-a-model.
