多模型合并可以实现以下功能：
- 覆盖多个模型以表现得像一个模型
- 统一访问数据，就像它是单个模型一样
- 只读。要修改模型的内容，您必须使用特定模型
- 不限于单个模式（联合IFC2x3 + IFC4→将其作为IFC4接口查询）
- IFC联合可以存储为单个IFC文件（在IfcStore中）
using System;
using Xbim.Common.Step21;
using Xbim.Ifc;
using Xbim.Ifc4.Interfaces;
namespace BasicExamples
{
public class FederationExample
{
public void CreateFederation()
{
var editor = new XbimEditorCredentials
{
ApplicationDevelopersName = "You",
ApplicationFullName = "Your app",
ApplicationIdentifier = "Your app ID",
ApplicationVersion = "4.0",
EditorsFamilyName = "Santini Aichel",
EditorsGivenName = "Johann Blasius",
EditorsOrganisationName = "Independent Architecture"
};
using (var federation = IfcStore.Create(editor, IfcSchemaVersion.Ifc4, XbimStoreType.InMemoryModel))
{
federation.AddModelReference("SampleHouse.ifc", "Bob The Builder", "Original Constructor"); //IFC4
federation.AddModelReference("SampleHouseExtension.ifc", "Tyna", "Extensions Builder"); //IFC2x3
Console.WriteLine($"Model is federation: {federation.IsFederation}");
Console.WriteLine($"Number of overall entities: {federation.FederatedInstances.Count}");
Console.WriteLine($"Number of walls: {federation.FederatedInstances.CountOf<IIfcWall>()}");
foreach (var refModel in federation.ReferencedModels)
{
Console.WriteLine();
Console.WriteLine($" Referenced model: {refModel.Name}");
Console.WriteLine($" Referenced model organization: {refModel.OwningOrganisation}");
Console.WriteLine($" Number of walls: {refModel.Model.Instances.CountOf<IIfcWall>()}");
}
// 保存为单一文件，工其他场景下使用
federation.SaveAs("federation.ifc");
}
}
}
}控制台输出如下所示：
Model is federation: True
Number of overall entities: 50303
Number of walls: 8
Referenced model: SampleHouse.ifc
Referenced model organization: Bob The Builder
Number of walls: 5
Referenced model: SampleHouseExtension.ifc
Referenced model organization: Tyna
Number of walls: 3保存为IFC文件的联合设置如下所示。这个惯例纯粹是我们的发明，所以它不适用于其他工具。但它允许您在系统中创建联合，并在需要时再次重新打开它们。
