Hello Luiscardoso,
An IFC file is a quite a hardly editable file. Is it a IFC4 or IFC2x3 ? Is it a coordination view or a design view ?
The question seems to be more what about your file instead of how are you able to modify it ?
If it's a IFC4 by design transfer view I think it might be easier to do what you want with it.
