Selecting Model Hierarchy for IFC Import and Export
In IFC import, you can omit the site, building, and floor information written to the IFC file in accordance with the standard, in which case the corresponding assembly levels are not created. In this case, the highest project level is replaced directly by the actual assembly level. As a result, the structure of the model corresponds to the way G4/G4Plant presents the structure of the assembly model. For IFC export, the standard site, building, and floor information can be omitted from the IFC file, if necessary.
