I am using REVIT Structure 2011. The ‘Structural Framing’ Family has been mysteriously removed from 2 of my models now. This happens in the middle of the project. I am working with only one other person in the model and neither of us are deleting the beams. They are all of a sudden missing from the model and when you look under the family the w8x10 is the only beam left. It's only losing the w-shape members. Any help is much appreciated.
Thanks
