Often we got projects with only ifc files. When publishing sheets by revit the only links that are visible in Sheet envrioment on ACC are the save cloud model links. For ifc you have to create a workaround where we first have to make from the ifc an ifc.rvt file that is also saved as cloud model. It would be much easier that this step can be eliminated by supporting IFC files that are within a revit project as a saved cloud model so you don't have to use the work around eachtime you get a new ifc.
