Using bimorph nodes today to speed up the process of converting a handful of DWG details downloaded from a manufacturer to Revit Detail Item Families, I ran into an issue with CAD.LayersInUse reporting an Empty List, which in turn caused CAD.DetailLinesFromCADLayers to fail:
The issue was resolved by restarting Revit and I am assuming it has something to do with changing documents, but I thought that restarting Dynamo would reconcile the document changes. I am hoping someone might explain to me what causes this? It isn’t entirely problematic for me given that running through several Family documents creating detail lines via Dynamo isn’t a daily task, and the time spent restarting Revit is considerably less than the time spent using Pick Lines to convert DWG details; I would just like to understand what is occurring.
Thanks in advance for any input
