While playing back and forth with Revit and Vasari this weekend I noticed a small little quirk (at least for me it’s a quirk).  Vasari doesn’t have an Insert tab on the Ribbon, so there isn’t a way to load a family into the current file.  You have to open the file and then hit “Load into Project”.  This is frustrating to me because in Vasari pretty much everything I am doing is a nested family.   I do know that I could always drag and drop the files from Windows Explorer but for me it was easier to the majority of the work in Revit and then open Vasari when I needed specific tools from it.  If I am missing the button or there is another way I would love to know.
