using System.Linq;
using Xbim.Ifc;
using Xbim.Ifc4.Interfaces;namespace BasicExamples
{class SpatialStructureExample{public static void Show(){const string file SampleHouse.ifc;using (var model IfcStore.Open(file)){var project model.Instances.FirstOrDefaultIIfcProject();PrintHierarchy(project, 0);}}private static void PrintHierarchy(IIfcObjectDefinition o, int level){Console.WriteLine(string.Format({0}{1} [{2}], GetIndent(level), o.Name, o.GetType().Name));// 只有空间元素可以包含建筑元素var spatialElement o as IIfcSpatialStructureElement;if (spatialElement ! null){// 使用 IfcRelContainedInSpatialElement 获取包含的元素var containedElements spatialElement.ContainsElements.SelectMany(rel rel.RelatedElements);foreach (var element in containedElements)Console.WriteLine(string.Format({0} -{1} [{2}], GetIndent(level), element.Name, element.GetType().Name));}// 使用 IfcRelAggregares 获取空间结构元素的空间分解foreach (var item in o.IsDecomposedBy.SelectMany(r r.RelatedObjects))PrintHierarchy(item, level 1);}private static string GetIndent(int level){var indent ;for (int i 0; i level; i)indent ;return indent;}}
