// Initialize ExporterIFC object ExporterIFC exporterIFC = new ExporterIFC(); // Get family name for an IFC entity string familyName = exporterIFC.GetFamilyName(entity); // Display family name Console.WriteLine("Family Name: " + familyName);In this example, we create an instance of the ExporterIFC class and call the GetFamilyName method, passing in an IFC entity. The method retrieves the name of the Revit family associated with the entity and stores it in the `familyName` variable. We then display the family name. This code example is part of the Autodesk.Revit.IFC.Export package library, which provides functionality for exporting Revit models to the IFC file format.
