I used the "IFC import" option to import an IFC-based object. However, when I import that file, a new project is created (instead of adding that imported object to my main project), and it does not allow me to copy that object to my main project. Also, Revit does not recognise the type of object (if I open the IFC file using notepad I can view that it belongs to "IFCFURNISHINGELEMENT", yet, in Revit that object does not have a family or a type).
