Revit Mass to Generic family


so im trying to get a revit mass geometry in to revit and them use FamilyInstance.ByGometry to create a generic family (at least i tough it will be that easy). the reason to do this is the flexibility that gives the mass environment vs the in place environment

Thanks for the Help Dimitar! i hope the nested famlies issue get fix soon.
