The standard format is IFC (Industry Foundation Classes), an open schema certified by buildingSMART. IFC ensures interoperability between different software solutions and allows models produced with Revit®, ArchiCAD®, Tekla®, Edificius and other BIM authoring software to be federated. Some solutions, such as usBIM.federation, also allow models in other formats to be federated, such as point clouds, EDF files modelled with Edificius, RVT, SKP, OBJ, etc.
