I created the model using a ModelBuilder connection to some ESRI shapefiles that I created from StormCAD. If there's any more information I can provide, please let me know.
If it is a bug, I assume there is no way to create an effective bi-directional link between my StormCAD and SUE models until it's fixed, correct? If there's any workaround that you can think of, please let me know.
Thanks!
Matt
