Revit has a problem grouping hosted families when the host has more than one hosted element in the group. Line-based families are particularly troublesome.
Instead of recreating all my LB families (ton of work) I’m thinking I could make the Group in the project, save it out to a new RVT file, and then run a Dynamo definition that created new host elements (Reference Planes would be ideal) and rehosted/recreated the families on these hosts.
I can create Planes in Dynamo but they’re not Reference Planes in Revit. The only RP creator I can see in Dynamo uses the Z axis. I need the X/Y. Even then I don’t see a way to rehost/recreate the family in this way. I can transform the coordinate system (not the same thing I fear), and I can create a lin-based family on a level but that defeats the purpose.
Thoughts?
