This is quite weird because revit architecture 2013 is showing this error. In order to see beam in my architectural layout, we are changing the cut plane value in the view range. With this step I can see the beam but not the cut pattern of the beam..very weird.
Also, one more thing, just to check I copy pasted beam modeled in revit 2011 in revit 2013 and I could see the cut pattern. So is something wrong with 2013 beam revit family?
