Just for the benefit of the forum the issue was resolved by running the following routines on this users model:
Please run the following routines in your model and it should fix your issue. All routines are in the InfoSWMM menu
- Utilities Database – Reindex
- Utilities Database- Pack
- Utilities Database – Clean
- Utilities -> Update Map form Database – Force All Network
Using these routines I was able to get all of the elements to appear properly. It appears something caused an issue with the index and it was causing things to not appear properly. These routines will fix the index issue and clear out the database of elements that have been deleted and will redraw the network properly.
