There is a error regarding "Other' material in Ram Connection 12.0 integration with RAM SS (Ram Modeler version 15.08) for any models that include horizontal braces.
(Error 6131) Error reading section properties for material type 'Other'.
Please confirm sections for material 'Other' have been created in RAM Modeler.
In other cases the error I is, "(Error 25613) Feature not Implemented"
Horizontal braces are a hybrid type entity behaving like beams in some cases and like braces in other cases. They are not being properly handled by Ram Connection.
Delete the model of any horizontal braces, or use a copy of the model.
Or revert to Ram Connection 11.2.
