To extract the DB.References from a Family Instance, refer here for a similar workflow:

Autodesk.Revit.DB.Reference to Curve

Hello Dynamo people. I want to create Room Boundary Lines at the location of the reference planes from a family. In the family I named the Reference Planes "Front"and “Back”.

Can anyone help me? Thanx in advance [Knipsel] import clr clr.AddReference("ProtoGeometry") from Autodesk.DesignScript.Geom…

I will post a full worked example in the morning.
