Hello, This is my problem. I put a Detail Item inside a beam family to simulate estructural rebar. The detail item contains detail lines simulating the stirrups and filled regions simulating longitudinal rebar. There is no problem when I load the family to the project. It is shown well. But if this beam cross other element like a wall or column, just the filled region (Longitudinal Rebar) disappear. Anyone know why this happens. Image and revit 2017 file are attached.


Thank you
