I am experiencing a problem with the DWF drawings that I am using to import to FM Desktop. It seems that wherever there are columns in the original Revit 9.1 drawings I end up with a line that connects the columns within a space and shows up in the DWF's. As I said, these lines connect the columns within a space and terminate on a wall in a seemingly random manner. This results in a drawing that is not very presentable in FM Desktop.
